GM Performance Parts is the industry leader in LS engine technology—remember that we are the factory. Our LS crate engine portfolio ranges from the super affordable LS327/327 all the way up to the new 638-horse LS9—the most powerful engine ever offered in a Chevrolet production vehicle, the Corvette ZR1. Our LS section starts on page 58. • LS Components - GM Performance Parts also offers the best way to get your LS engine running in your project vehicle with our LS Controller and Harness kits.

These engines offer uncompromised components, state-of-the-art engineering and testing, and a truly superior performance to anything else in the LSX market.

Our engineers have redesigned the Chevy Big-Block so that all of your Mark IV and Gen VI components will work with one engine block. This block will become the standard block for several GM Performance Parts Big-Block crate engines, like the ZZ454/440 and ZZ502. Read all about it on page 228. • More Small-Block Chevy engines than anyone - GM Performance Parts continues to offer the automotive enthusiast more choices in Small-Block Chevy crate engines than anyone else in the industry. Remember, we invented the Small-Block and have perfected it with the 350/290, Ram Jet 350, ZZ4 350, ZZ383, and dozens of other Small-Block combinations. Now, more than ever, you have to be confident in the quality of the speed parts that you buy.

For more than 40 years, GM Performance Parts has been your No. 1 choice for GM high-performance crate engines and engine components for several reasons. First, we are the factory, and our engineers follow the same strict engineering, testing and validation procedures that GM developed for vehicle manufacturing.

The Chevrolet Camaro returns to production in 2009 after a seven-year hiatus. It hits the streets as a 2010 model and carries more than heritageinspired design. The new Camaro is a true sports car of the 21st century, blending great performance and styling with advanced technology and surprising efficiency. In short, it delivers on the expectations of enthusiasts old and new, is competitive with the world’s best and is wrapped in an instantly recognizable design. The Camaro is offered in V-6-powered LS and LT models, along with the next-generation muscle car, the Camaro SS. It’s powered by the LS3 6.2L, all-aluminum V-8 and rated at 422 horsepower (with the manual transmission). All models and powertrain combinations include six-speed transmissions—either manual or automatic—that better match power to rpm for a greater feeling of performance, as well as better fuel economy. Engines paired with an automatic transmission, known by the L99 engine code, also feature GM’s fuel-saving Active Fuel Management system, which deactivates half of the engine’s cylinders in light-load driving conditions, such as highway cruising. And while the LS3 is unquestionably a powerhouse engine, the LS and LT models’ advanced 3.6L engine is a potent performer in its own right. It uses gasoline direct injection and a high, 11.3:1 compression ratio to make 304 horsepower. Variable valve timing optimizes power and fuel economy across the rpm band, while the direct injection system significantly reduces cold-start emissions. Chevrolet estimates V-6-powered Camaro models should cover the quarter-mile in the mid- to high-14-second range at approximately 100 mph—that’s equivalent to the performance of LT1-powered Z28 models of the early 1990s. The LS3-powered Camaro SS is projected to launch down the drag strip in the low- to mid-13s at approximately 110 mph. 4 Camaro, as dozens of factory options, Chevrolet Accessories and GM Performance Parts components are offered. Each is designed to enhance the appearance, performance or comfort of the Camaro. (See the Camaro Performance and Accessories section on page 322 for the parts to bolt onto your new Camaro.) Additional highlights of the new Camaro include: • V-6 models offered with an Aisin Warner AY6 six-speed manual or Hydra-Matic 6L50 six-speed automatic • SS model offered with a Tremec TR6060 six-speed manual or a Hydra-Matic 6L80 six-speed automatic • Four-wheel independent suspension system, including a 4.5-link rear suspension • Variable-rate power steering with the rack mounted forward of the front axle for greater driver feel • Four-wheel disc brake systems standard on all models, including four-piston, fixed Brembo calipers on SS models • StabiliTrak™ stability control system and traction control standard on all models • Competitive/sport modes for the stability system offered on SS models, including launch control on SS models equipped with the six-speed manual transmission • Detailed interior with heritage-inspired design, excellent attention to detail and available ambient lighting via LED light pipe technology • Standard side curtain air bags and front-seat pelvis/thorax side air bags More than the sum of its features, the new Camaro is remarkable for its superior build quality and attention to detail. Single-piece side body stampings, for example, help form a stronger body structure and enable a more precise assembly. Minimal gaps between panels and features such as automatic indexing of the frameless door windows are evidence the new Camaro is built to an unprecedented level of refinement. There are wonderful details throughout, too, like an available interior center console that evokes the look of a similar option on 1969 models, including four rectangular gauges. The new Camaro also has technologies that enhance performance, comfort and convenience, including: • • • • • • • Bluetooth phone connectivity Premium Boston Acoustics audio system USB connectivity Head-up display Ultrasonic rear parking assist Remote vehicle starting system OnStar Heritage Design At a glance, there’s no mistaking the 2010 Camaro for any other car, but it also reflects a modern design ethic that uses heritage cues to accentuate a completely contemporary proportion. Elements such as a forward-V shape at the front of the car and “gills” in front of the rear fenders are distinctly Camaro features, as are the broad rear fender “shoulders.” LS and LT models are offered with 18- and 19-inch wheels, while the SS comes standard with 20-inch wheels. An available RS package adds further exterior distinction, including HID headlamps, a rear spoiler, specific taillights and more. A well-executed balance of heritage, modern design and attention to detail also characterizes the Camaro’s interior. A pair of deeply recessed instrument binnacles that feature round gauges in square housings is a nod to classic Camaros, while details such as large, chrome-trimmed controls; low-gloss surfaces; LED ambient and backlighting; and premium materials convey a richness that is unprecedented in previous Camaro models. Help From Down Under Development of the new Camaro was truly a global affair. With the idea and initial design concepts originating in the United States, the bulk of the vehicle’s development was spearheaded by GM’s engineering team in Australia—the same team that developed the new, rear-drive platform on which the Camaro is built. It was introduced in North America on the Pontiac G8, but is also used in markets around the world. Production takes place at GM’s worldclass facility in Oshawa, Ontario, Canada. Designed for personalization When it was introduced in 1967, the Camaro’s success came not only in its distinctive design and performance, but the seemingly endless range of options that encouraged owners to personalize their cars. That spirit of personalization returns with the 2010 Buy online at www.gmperformanceparts.com 2010 Camaro Specifications Dimensions ENGINE LS/LT SS Wheelbase (in): 112.3 Track, front (in): 63.7 Type 3.6L SIDI VVT (LLT) 6.2L V-8 (LS3/L99) Overall height (in): 53.8 Track, rear (in): 64.1 (LS/LT), 63.7 (SS) Cylinder block Cast aluminum Cast aluminum Overall length (in): 189.6 Curb weight (approx lbs): 3750 (LS) Bore (in / mm) 3.70 / 94 4.06 / 103.25 Stroke (in / mm) 3.37 / 85.6 3.62 / 92 Displacement (cu in / cc) 217 / 3564 376 / 6162 Cylinder heads Aluminum Aluminum Compression ratio 11.3:1 10.7:1 Valvetrain DOHC, variable valve timing OHV; Active Fuel Management (L99) Ignition system Distributorless, coil-near-plug Distributorless, coil-near-plug Fuel delivery High-pressure direct injection Returnless, multi-port injection Horsepower (@ rpm) 304 @ 6400 422 @ 5000 (LS3) Torque (lb-ft @ rpm) 270 @ 5200 408 @ 4500 (LS3) Overall width (in): 75.9 3775 (LT), 3900 (SS) Chassis / Suspension Front: Multi-link MacPherson strut with direct acting stabilizer bar; progressive-rate coil springs and fully adjustable camber, caster and toe Rear: Multi-link independent; progressive-rate coil springs over shocks; fully adjustable camber and toe Steering: Variable-ratio rack-and-pinion Steering ratio: 16.1:1 Transmissions/Axles LS/LT SS Six-speed manual Aisin Warner AY6 Tremec TR6060 Brakes LS/LT SS Six-speed automatic Hydra-Matic 6L50 Hydra-Matic 6L80 Type 4-wheel disc w/ABS 4-wheel disc w/ABS Final drive ratio 3.27 3.45 (man); 3.27 (auto) Calipers, front Single-piston, iron 4-piston, aluminum Brembo Calipers, rear Single-piston, aluminum 4-piston, aluminum Brembo Wheels / Tires LS/LT SS Rotor diameter, front (in) 12.64 14.00 Wheel size (in) 18 x 7.5 (LS) or 19 x 8 20 x 8 (front); 20 x 9 (rear) Rotor diameter, rear (in) 12.40 14.40 Tires P245/55R18 P245/45R20 (front) P245/45R19 P245/40R20 (rear) Buy online at www.gmperformanceparts.com 5 PERFORMANCE CENTER NEWS LSX Shootout–The Fastest Guns of a New Generation Order Your GM Performance Parts Crate Engines and Components Online! The GMPP-backed and NMCA-sanctioned LSX Shootout is quickly becoming a must-do event for racers running GM’s LS engine family.

GM Performance Parts has a new online superstore that simplifies shopping for high-performance engines, parts and components. Visit it at: www.gmperformanceparts.com.

We’ll see you there! A sample of the parts and services available includes: The Ultimate Crate Engine Test Last summer, GM Performance Parts teamed up with Hot Rod Magazine for a performance test unlike anything ever attempted. During four days of furious wrench-turning and lots of VHT, at U.S. 131 Dragway, in Martin, Michigan, we swapped eight crate engines—Small-Block, Big-Block and LS Series—into a race-prepared 1969 Chevelle. We then made dozens of brutal quarter-mile passes in the ultimate validation session for our crate engines. here are the quickest times for each engine family: We leaned hard on the Chevelle and pushed our engines to their limit. The car wore 28 x 10.5-inch tires and was equipped with a DTS 9-inch rearend (for quick gear changes) and a TCI Automotive Pro-X Turbo 400. The gears and torque converters were changed as necessary to match the various engines. When the last timing light was tripped and the rubber dust settled, we learned much about the performance of our engines. It was information we took back to our engineers to improve existing products and guide the development of new ones. You can check out the October 2008 issue of Hot Rod for a complete, 20-page diary of our demonic demonstration, but • Nearly 40 genuine GM Small-Block, Big-Block and LS Series highperformance crate engines • More than 300 different part numbers available for sale in one place: engines, blocks, heads, cams, intake manifolds, accessory drives and dress-up parts • Product search capability by category, name and part number • Complete product information descriptions of all GMPP products • Technical product information, including dyno charts, tech specs and engine builds • Pricing—GM’s MSRP and access to dealer’s retail pricing Getting started shopping for GMPP engines and components is easy.

From hidden rust in vintage sheet metal to new rules in your racing class, you can only be certain of the uncertainty when it comes to building cars and trucks. Powering your muscle car, street rod, race car or off-roader isn’t an exercise in the unknown when you select a GM Performance Parts crate engine. They’re designed by General Motors engineers who live, breathe and dream about GM engines. GM Performance Parts’ engine families—Small-Block, Big-Block, Circle Track, LS and LSX—offer an unmatched range of choices, performance levels and value. And our turn-key engines include the components required to get the engine started the day it is delivered. We also offer dozens of chrome and dress-up items that enable you to personalize an engine to make it uniquely yours. Every GM Performance Parts crate engine is designed to deliver excellent, all-around performance. We don’t sacrifice drivability to claim a bigger horsepower number. We also don’t sacrifice time when it comes to testing. Each engine undergoes 50 hours of high-load durability testing, as well as real-world validation in GM Performance Parts’ fleet of project vehicles. We use ’em how you’ll use ’em—and then some! There’s another advantage to GM Performance Parts crate engines that competitors can’t match: all-new parts—including the cylinder block. Other aftermarket crate engines use reconditioned or rebuilt cores, but GMPP crate engines use brand-new blocks, heads and internal components. We back up our all-new crate engine combinations with a 24-month warranty (street engines only). Sure, your vehicle project is going to throw you some curves, but you can eliminate the guesswork under the hood by selecting a factory-engineered high-performance crate engine from GM Performance Parts. 8 9 CRATE ENGINES Crate Engine Quick Reference Chart CHEVy SMaLL-BLoCk V-8 part number Description 12499529 350/290 HP—Economy Performance Engine 19201328 350 HO Turn-Key—with Iron Vortec Heads 19201329 350 HO Deluxe—with Iron Vortec Heads 12486041 350 HO Base— with Iron Vortec Heads 19201330 ZZ4 350 Turn-Key — with Aluminum Heads 24502609 ZZ4 350 Base—with Aluminum Heads 12561723 ZZ4 350 Partial Engine 12499120 Ram Jet 350 —PFI with Iron Vortec Heads 19201331 Fast Burn 385 Turn-Key— with Aluminum Vortec Heads 12496769 Fast Burn 385 Base—with Aluminum Vortec Heads 12499101 HT383 Base—Performance Engine 12499106 383 Partial Engine 17800393 HT383E 12498772 ZZ383 with Aluminum Vortec Heads engine size 350 cu in 350 cu in 350 cu in 350 cu in 350 cu in 350 cu in 350 cu in 350 cu in 350 cu in 350 cu in 383 cu in 383 cu in 383 cu in 383 cu in weight 352 575 481 298 511 379 223 517 511 466 405 335 450 397 Hp 290 330 330 330 355 355 N/A 350 385 385 340 N/A 340 425 torque 326 380 380 380 405 405 N/A 400 385 385 435 N/A 435 449 page 40 42 43 43 44 45 45,49 46 48 49 50 51,55 52 54 warranty LS FaMILy SMaLL-BLoCk V-8 part number Description 19165628 LS327/327 17801267 LS1 5.7L—Without ECU and Wire Harness 17801268 LS6 5.7L—2004 Corvette Z06 Gen III V-8 12611022 L99 6.2L AFM 19201992 LS3 6.2L—2008 Corvette Gen IV V-8 19213229 LS376/480—EFI LS3 Gen IV V-8 19171225 LS376/515—Carbureted LS3 Gen IV V-8 19211708 LSA 6.2L SC 19201990 LS9 6.2L SC 19211710 LS7 7.0L—2006 Corvette Z06 engine size 5.3L 5.7L 5.7L 6.2L 6.2L 6.2L 6.2L 6.2L 6.2L 7.0L weight 433 409 464 Hp 332 350 405 TBD 429 480 515 556 638 505 torque 352 365 400 TBD 424 475 469 551 604 470 page 60 62 64 66 68 70 72 74 76 78 warranty 415 415 415 440 GM Performance Parts Crate Engines include a 24-month or 50,000-mile limited warranty.

The deluxe crate engines are essentially ready to fire up, as they ship with the distributor installed, harmonic balancer bolted on and the carburetor in the crate. All you need to do is put the parts together and go! The base engine assembly typically includes, block, crank, pistons, cam, heads and valve covers, but allows the builder to pick the carburetor/injection system and intake manifold they desire. We told our engineers to have some fun and assemble engines the way they think it should be done … we then took their combinations, built them up and put them in a crate that ships right to your dealer. The turn-key engines represent an outstanding value, and they are perfect for enthusiasts who have built a chassis and need reliable power to get it down the road.

Its compact and efficient design—defined by 4.40-inch bore centers—delivered exceptional performance in lower-priced cars. The Small-Block V-8 was an immediate hit and by the mid-1960s, it was at the forefront of the burgeoning muscle car movement. And when a compact performer named the Camaro hit the scene in 1967, the Small-Block found its spiritual home, be it the original 302-inch-powered Z28, the high-winding LT1 of the early 1970s or the Tuned-Port Injection models of the 1980s. 38 During its more than 50 years, the Small-Block has evolved with surprising agility, responding greatly to technology unheard of in 1955. Through it all, the Small-Block remained the people’s V-8—whether a budget cruiser for a high-school enthusiast or the power plant for a championship street rod. It is the undisputed choice for countless builders. The Small-Block Chevy is the classic V-8, and GM Performance Parts honors it with a range of Small-Block crate engines to suit every budget and horsepower desire. We’ve also got the chrome accessories to dress yours perfectly—be it a 1957 Chevy, ’69 Camaro, street rod or truck. 39 CRATE ENGINES SMALL-BLOCK 350/290 HP CRATE ENGINES SMALL-BLOCK 12499529 Our best crate engine value delivers all you expect in a powerful small-Block! The most affordable GM Performance Parts Small-Block crate engine is also our best seller—and it’s easy to understand why. The 350/290 HP Small-Block features four-bolt mains for strength and makes a great economical alternative to rebuilding a tired, two-bolt main core. Use to re-power your daily driver or drop it in your budget Camaro project! Inside the 350/290HP are quality parts, including a camshaft and durable aluminum pistons that squeeze an 8.5:1 compression ratio. We deliver the 350/290HP in base form, allowing you to add the induction and other accessories. That’s great for builders swapping over the intake manifold, carburetor and other components when re-powering a vehicle. GM Performance Parts has all the components to build up the 350/290 HP into a high-performance, great-looking street engine, too—from an aluminum intake and carburetor (we recommend the 670-cfm Holley four-barrel, P/N 19170092) to the distributor, water pump and more.

Crate engines don’t come more complete than the classic 350 HO Turn-Key. Rated at a strong 330 horsepower and 380 lb-ft of torque, it is the perfect replacement for a tired engine in an otherwise stock vehicle, or a great power plant for a budget-conscious street machine, street rod or off-roader. The 350 HO features a tough four-bolt main cylinder block, torque-building Vortec iron heads (with center-style valve cover hold-downs), and a responsive hydraulic flat tappet camshaft with 0.435/0.460 lift specs, which gives the 350 HO an aggressive idle that sounds wholly appropriate in a ’67 Camaro with a set of Cragar S/S wheels. Because the 350 HO is a Turn-Key crate engine, it comes with the intake manifold and distributor already installed. Additional accessories, including a front-accessory drive kit, carburetor, starter, fuel pump and even spark plug wires, are included in the package. It’s the perfect crate engine, whether you’re building a 1972 Malibu, home-grown street rod or mid-1970s pickup.

Whether you’re building a vintage Camaro for cruise-night duty, a mid1970s G-body for the strip or early full size car in need of some serious grunt, the ZZ383 delivers Big-Block-style performance. Using the sturdy 383 bottom end—including four-bolt mains, a forged crankshaft and heavyduty rods—we topped it with Fast Burn cylinder heads to enable 425 horsepower and 449 lb-ft of torque (when finished with high-rise intake P/N 12496822 and a Holley 770-cfm four barrel, P/N 19170093). The Fast Burn heads use high-flow intake runners, 2.00/1.55-inch valves and a unique combustion chamber design to process air quickly and efficiently. A roller camshaft with more than 0.500-inch lift on both the intake and exhaust sides helps this potent engine maximize airflow.

Sharing only a 4.40-inch bore center dimension with the original Chevy Small-Blocks, the LS series engines represent state-of-the-art design and manufacturing. And with features such as crank-triggered ignitions, “dry” assembly techniques and tremendous parts interchangeability, these productionbased engines make smart choices for enthusiasts seeking a powerful solution to their project engine needs. GM Performance Parts has a great selection of LS crate engines. They range from economical, production-based 58 GMPP_2009_Pages058-089_final_rev.indd 58-59 packages that make great swap material for late-model Camaros, Corvettes, GTOs and more (off-road use only, of course!) to purpose-built high-performance engine packages— with fuel injection or carburetion—that are designed to give your vintage car the easy-driving attributes and efficiency of a modern engine. The good-old days were fun. But they were never as good – or promising – as the performance delivered by the LS series. It’s a new generation of performance for a new generation of enthusiasts. 59 11/21/08 3:55:51 PM CRATE ENGINES LS SERIES Available for purchase online at gmperformanceparts.com LS327/327 CRATE ENGINES LS SERIES 19165628 a classic combination built with modern ls technology Reverence for GM’s powertrain heritage has always been part of the LS engine family’s legacy, from the same 4.40-inch bore centers found on the original Small-Block to acknowledgements of past engines, as seen in our LS327/327 crate engine. It’s a 5.3L LS power plant with the same 327-cubicinch displacement of the high-winding Small-Blocks from the 1960s. Introduced in 1962, the 327 was found in everything from fuel-injected Corvettes to the very first Camaros. It was renowned for its high-rpm performance and surprising torque from a comparatively small-displacement V-8. Our powerful and economical LS327/327 crate engine delivers a strong 327 horsepower and 347 lb-ft of torque. It is based on the 5.3L engine used in thousands of GM trucks and SUVs, but it is “breathed on” by GM Performance Parts engineers with a hotter cam, Grafal-coated high-silicon pistons and more. An iron block reinforces the engine’s strength and keeps down the cost, making it the perfect combination for re-powering your truck (depending on the emissions regulations in your area) or dropping a budget LS engine into your classic vehicle or street rod.

Just like the 350 is the quintessential Small-Block, so is the storied LS1 to the LS engine family—it’s the engine that started the LS revolution. It was introduced in the 1997 Corvette and quickly spread to the ’98 Camaros and Firebirds. And while we at General Motors dubbed the new engine family “Gen III,” it was the enthusiast community that seized on the first two letters of the LS1 name and gave the widely used “LS” family nickname. At the core of the LS1 is an aluminum deep-skirt cylinder block with six-bolt main caps; an oil pan that is a structural component of the assembly; aluminum cylinder heads with cathedral-style ports and 2.00/1.55-inch valves; and a crank-triggered ignition system with eight individual ignition coils. GM Performance Parts offers the LS1 crate engine in dressed, regularproduction form. That includes a manifold assembly with the fuel injectors, fuel rails and an electronically controlled throttle body already installed; a Holden oil pan, complete ignition system; exhaust manifolds; balancer; water pump; and a 14-inch automatic-transmission flexplate. affOrdaBle hiGh-PerfOrMaNce aluMiNuM caThedral-POrT heads 350 hP / 365 lB-fT TOrque INSTALLATION NOTES • 14-inch automatic transmission flexplate included • Assembly does not include any electronics • Includes Holden oil pan • Intended for pre-1976 street vehicles or any off-road vehicle • Not intended for marine applications • Non-Corvette applications require flexplate P/N 12602448 The LS1 crate engine is an affordable performer to re-power your fourthgeneration F-car, add a high-tech twist to your vintage Camaro or give a powerful advantage to your off-road crawler!

Introduced on the 2001 Corvette Z06, the LS6 was the hottest, most powerful GM engine since the muscle car heyday. Based on the LS1 5.7L engine, the LS6 used a unique block casting with better cylinder bay-to-bay breathing; a higher-lift camshaft with correspondingly stronger valvetrain components; higher compression; an integral PCV system and more. In its original 385-hp form, it was powerful enough to shoot the Z06 from 0-60 in four seconds flat and through the quarter-mile in about 12.5 seconds. GM Performance Parts’ LS6 5.7L crate engine is based on the 405-hp version used in 2002-2004 Corvette Z06 models and the 2004-2007 Cadillac CTS-V, with a robust 395 lb-ft of torque. It comes with a CTS-style oil pan and production-type log exhaust manifolds.

The Camaro is back and better than ever! The 2010 Camaro hits the pavement in ’09 with heritage styling, an aggressive stance and tire-smoking LS power under the hood—and you can put that new-generation performance to work in your project car with the new Camaro’s L99 V-8 engine for use with automatic transmissions. Nearly identical in performance and construction to the Camaro’s manualtransmission LS3 engine, the L99 engine is equipped with GM’s fuelsaving Active Fuel Management (AFM) technology. AFM enables the engine to cut off fuel to half of the cylinders in certain light-load driving conditions, such as highway cruising, to reduce fuel consumption. Special lifters are used on the deactivating cylinders, effectively turning the engine into a V-4 (the remaining cylinders pump only cooling air). The changeover between V-8 and V-4 performance is virtually imperceptible.

Inside, the LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.551-inch of lift on the 2.165-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves. It holds those valves open for 204-degrees of rotation (intake) and 211-degrees (exhaust), respectively, enhancing the LS3’s tremendous airflow and table-flat torque curve.

Just like you, GM Performance Parts engineers spend much of their time wondering about the “what if” combinations when it comes to mixing and matching LS engine components—and they have the tools and facilities to act on those instincts. That’s how we created the exciting LS376/480 crate engine! Our power-mad engineers started with the production LS3 6.2L (376 cubic-in) engine—including its rectangular-port L92-style heads—and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958733) and the result was nothing short of astonishing. With no other modifications, horsepower jumped from 430 to 480 and torque rose from 424 lb-ft to 475—that’s about 12 percent more power and torque from a simple camshaft change! The key to the power boost is the Hot Cam’s 0.525-inch lift on both the intake and exhaust sides, along with 219-degree/228-degree duration specs. That’s less lift on the intake side than the stock LS3 cam, but considerably more duration, allowing the valves to stay open a little longer to draw in more air. As a result, peak horsepower comes earlier than the stock LS3 and the torque curve remains flat higher on the rpm band.

By combining traditional carbureted aspiration with the high-tech attributes of the LS platform, we’ve developed the ultimate modern engine for your vintage car or truck—or race car. It’s the LS376/515! With the LS3 engine as its foundation, the LS376/515 crate engine uses the regular-production bottom end, including an aluminum block with six-bolt cross-bolted main caps, a Corvette oil pan and LS3 cylinder heads with high-flow, rectangular-port intake passages. To that, we swap the fuel injection system for a high-rise intake manifold of our own design, a 770-cfm carburetor (sold separately) and our race-tested ASA Hot Cam, P/N 12480110. The new combination is worth 515 horsepower at a stellar 6500 rpm and 469 lb-ft of grin-inducing torque at 5000 rpm. Compared to the regular-production LS3 and even our LS3-based LS376/480 crate engine, the ASA Hot Cam gives this combination much more camshaft duration to hold open the valves longer. It’s a horsepower-building camshaft designed for the wide-open, high-rpm world of circle track racing and it means big power for this great crate engine—whether it’s used on the street or track. lONG caMshafT duraTiON hiGh lifT fOr TreMeNdOus POwer 515 hP / 469 lB-fT TOrque INSTALLATION NOTES • 14-inch automatic transmission flexplate included • Assembly does not include any electronics • Use LSX ignition controller P/N 19171130 (page 288) • Includes Corvette wet sump oil pan • Intended for pre-1976 street vehicles or any off-road vehicle • Not intended for marine applications • 770-cfm carb P/N 19170093 recommended for daily street use • Non-Corvette applications require flexplate P/N 12602448 See page 300 for information on our reference guide P/N 88959384 for installing an LS engine in an older car. ls376/515 dyno chart Possible aPPlications* Put an ls engine where that old small-Block used to be 72 GMPP_2009_Pages058-089_final_rev.indd 72-73 GM Performance Parts Crate Engines include a 24-month or 50,000-mile/80,000-kilometer limited warranty.

The 2009 Cadillac CTS-V ups its performance game with an all-new, 6.2L supercharged LSA engine that delivers 556 horsepower—making it second only to the Corvette ZR1’s LS9 supercharged engine as the most powerful production LS crate engine offered by GM Performance Parts. It is based on the same foundation as the LS9, but with a slightly smaller supercharger and a few other unique components designed to deliver Cadillac’s signature quietness and refinement. But just because the LSA doesn’t have the same peak power numbers of the LS9 engine doesn’t mean it comes up short in any important measurement. The unique aluminum-cylinder block casting houses a forged steel crankshaft and super-tough reciprocating parts, integrated pistoncooling oil jets, high-flow cylinder heads and relatively mild camshaft with 0.492-inch lift on both the intake and exhaust sides. The forced induction of the 1.9L, sixth-generation supercharger makes up for the comparative lack of valve lift by packing the combustion chambers full of air and fuel. This gives the LSA 556 horsepower and 551 lb-ft of torque, along with excellent idle quality and “right-now” throttle response. And unlike the LS9, the LSA comes with a conventional wet-sump lubrication system. uNique 1.9l suPercharGer free flOwiNG cyliNder heads 556 hP / 551 lB-fT TOrque INSTALLATION NOTES • 14-inch automatic transmission flexplate included • Assembly does not include any electronics or accessory drive components • Includes Corvette wet sump oil pan • Intended for pre-1976 street vehicles or any off-road vehicle • Not intended for marine applications • Non-Corvette applications require flexplate P/N 12602448 See page 300 for information on our reference guide P/N 88959384 for installing an LS engine in an older car.

The new LS9 6.2L supercharged—the standard engine in the 2009 Chevrolet Corvette ZR1—is a technology marvel that holds the distinction of being the most powerful regular-production engine ever offered in a GM car. It helps propel the 3,324-pound ZR1 from 0-60 in 3.4 seconds and through the quarter-mile in an astonishing 11.3 seconds at 131 mph—all the way to a top speed of 205 mph! Those stats make the ZR1 not only the most powerful car ever from GM, but the quickest and fastest, too! GM Performance Parts is thrilled to offer the LS9 6.2L in a fully dressed crate engine package. And while it shares the 6.2L displacement of other LS engines, this one is unique, with stronger block casting, stronger cylinderhead castings and steel cylinder liners that are honed with a deck plate installed to maximize performance and cylinder sealing. High-rpm-validated lightweight reciprocating parts, including titanium intake valves and connecting rods, are used along with high-flow cylinder heads that flow the charge forced on them by a sixth-generation supercharger. A revised, higher-helix design delivers greater power at the low end and sustains it longer through the rpm band for broad, on-demand power whether off-idle or at speed. A dual-brick charge cooler is integrated on a unique manifold system that mounts the “blower” in the engine’s valley, with charge cooler on top. fully dressed craTe eNGiNe sixTh-GeNeraTiON suPercharGer 638 hP / 604 lB-fT TOrque INSTALLATION NOTES • 14-inch manual transmission flywheel included • Assembly does not include any electronics • Includes Corvette dry sump oil pan - requires production or aftermarket oil lines and oil tank (not included) • Intended for pre-1976 street vehicles or any off-road vehicle • Not intended for marine applications • Crankshaft has unique 9-bolt flywheel mounting pattern See page 300 for information on our reference guide P/N 88959384 for installing an LS engine in an older car. ls9 dyno LS9chart DYNO CHART Possible aPPlications* 700 Build your own Zr1 600 500 400 300 200 00 44 00 46 00 48 00 50 00 52 00 54 00 56 00 58 00 60 00 62 00 64 00 66 00 00 42 40 38 00 100 Horsepower: 638 @ 6500 rpm Available for purchase online at gmperformanceparts.com 76 GMPP_2009_Pages058-089_final_rev.indd 76-77 ls9 tech sPecs Cylinder Heads (P/N 12621774): Aluminum L92 style ports; Part Number: 19201990 a ‘69 camaro with the ultimate Vette engine Engine Type: LS Series Gen IV Small-Block V-8 Displacement (cu in): 376 cu in (6.2L) Valve Size (in): 2.16 intake / 1.59 exhaust any 4th-Gen f-body that deserves 600+ horsepower Bore x Stroke (in): 4.06 x 3.62 (103.25 x 92mm) Compression Ratio: 9.1:1 Block: Cast-aluminum with 6 bolt, Rocker Arms (P/N 12569167 int): Investment-cast, roller trunnion cross-bolted main caps Rocker Arms (P/N 10214664 exh): Investment-cast, roller trunnion Crankshaft (P/N 12598610): Forged Steel Rocker Arm Ratio: 1.7:1 Connecting Rods (P/N 12624231): Forged titanium Recommended Fuel: 92 octane Pistons (P/N 12598634): Forged aluminum Maximum Recommended rpm: 6600 Camshaft Type (P/N 12605527): Hydraulic roller Reluctor Wheel: 58X Valve Lift (in): .562” intake / .558” exhaust Balanced: Internal Camshaft Duration (@.050 in): 211° intake / 230° exhaust *Applications have not been validated.

After only a few short years, the LS7 7.0L engine of the Corvette Z06 is a legend in its own time. Sure, it’s got more than 500 naturally aspirated horsepower and 470 lb-ft of torque, but the exceptional high-rpm performance and low-end grunt gives this 427-cubic-in combination the great tractability for which LS engines are known and the pulling power expected of a Big-Block with its historic displacement. The LS7 features a unique big-bore cylinder block that is anchored with a forged crankshaft, featherweight titanium connecting rods and durable, friction-coated pistons. But it’s the airflow capability of the LS7’s cavernous, CNC-ported heads that enables its tremendous power. Large-volume, straight-passage intake runners channel air directly through 2.20-inch titanium intake valves. The mixture is burned in large, 70cc combustion chambers and what’s left exits through 1.61-inch sodium-filled exhaust valves. And did we forget to mention the dry sump oiling system? This is a serious engine for serious enthusiasts. GM Performance Parts’ LS7 7.0L crate engine package includes a productionstyle engine with the dry sump oil pan.

Based on the basic design of GM’s modern LS family of V-8 engines, it was designed to give builders an economical yet exceptionally strong foundation on which to build extreme-performance engines. The LSX376 uses the LSX Bowtie block, new LSX forged pistons and combines them with the heads and other components of the LS3 engine for an affordable power house. The LSX454 is a modern interpretation of a classic combination that over-delivers on the promise of its Big-Block displacement. But the LSX block was just the beginning. Our engineers have been busy developing high-performance engine combinations; and for 2009 GM Performance Parts is proud to introduce the first two LSX crate engines—the LSX376 and LSX454. These new crate engines offer great performance and value, but our engineers are just getting started with LSX performance. 82 GMPP_2009_Pages058-089_final_rev.indd 82-83 83 11/21/08 4:06:38 PM CRATE ENGINES LSX SERIES Available for purchase online at gmperformanceparts.com LSX376 CRATE ENGINES LSX SERIES 19171049 the affordable lsX crate engine has arrived! GM Performance Parts takes the economical LSX Bowtie block and combines it with the LS3’s high-flow L92-style heads and mostly internal components (we swap the pistons for forged parts), to create the affordable, high-revving LSX376 crate engine. It represents the essence of LS performance—exceptional airflow capability in straightforward packaging that delivers huge performance without a power-adder. We deliver the LS376 without an intake manifold (and other accessories). So, whether you top the engine with a carburetor or production-style injection system, it’s suitable for your street rod, ’57 Chevy or ’71 Camaro —be it on the street or strip. Our horsepower and torque ratings are based on using the productionstyle injection system. More power can be realized by swapping that for one of our carburetor intakes and a well-tuned Holley four-barrel.

You see it in the quivering four-inch-tall cowl scoop of the fiberglass hood. You hear it the muffler-straining note of the sewer-pipe exhaust. You feel it in your chest, as if all eight coffee cansized pistons were thumping directly on it. You smell it in the sweetness of the high-octane exhaust. And you taste it as the bitterness of defeat if you’re packing anything less than a BigBlock yourself. 90 The Big-Block isn’t just an engine. It’s a tactical weapon used by those who lurk on the edges of the night, rumbling around in cars with primered fenders and fuel pumps hanging below the rear bumpers. It’s not flashy, but the Big-Block has never been about winning awards. It’s about ensuring there’s no way the other guy is going to get around you. 91 CRATE ENGINES Big-Block ZZ427/480 CRATE ENGINES BIG-BLOCK 19166393 A modern interpretation of the legendary l88 427 Between 1967 and 1969, the alphanumeric designation that struck fear from Main Street to the drag strip was L88. It was the ultimate expression of Chevy’s Big-Block power, combining a rigid iron cylinder block with lightweight aluminum cylinder heads and a single four-barrel carburetor. GM Performance Parts has recreated that classic Big-Block combination in the ZZ427/480, rated at 480 horsepower. Like the original, it features an iron block, forged steel crankshaft and high-flow aluminum cylinder heads. We’ve upgraded the camshaft from the original’s mechanical flat-tappet design to a more contemporary hydraulic roller, giving this 21st-century L88 modern drivability characteristics and a greater rev range. A lower 10.1:1 compression ratio makes it pump gas-friendly, too. The original L88, born in the time of leaded gasoline, had 12.5:1 compression. The ZZ427/480 comes complete with high-flow oval-port heads, a highlift camshaft (0.510-inch intake/0.540-inch exhaust), an aluminum intake manifold, 870-cfm Holley carburetor, an HEI distributor, aluminum water pump, balancer, spark plug wires and a 14-inch flexplate. Whether you’re building a ’69 COPO Camaro resto-mod tribute, a modified mid-year Corvette or a street-tire class winner, the ZZ427/480 is the heritage-inspired crate engine that delivers the performance that built the Big-Block’s legendary reputation. zz427/480 dynO CHArt updated classic comBination HigH-flow oval-port Heads 480 Hp / 490 lB-ft torque INSTALLATION NOTES • Due to crate fitment, the carburetor is shipped in a separate box and needs to be installed by an engine installer • Requires addition of starter and fuel pump (not included) • Clutch linkage bosses are drilled and tapped.

And while their intent was to dominate the popular Super Stock drag racing classes, they touched off what would become one of the colorful chapters in the muscle car anthology. silver powder-coated valve covers The special cars—two Corvettes and 69 Camaros—were equipped with an all-aluminum 427 engine dubbed the “ZL1” that was largely similar in specification to the vaunted L88 427, but with an aluminum block that saved about 100 pounds off the cars’ nose-heavy front-ends. The engine was officially rated at 430 horsepower, but the true output was closer to 500 horses. 430 Hp / 444 lB-ft torque GM Performance Parts commemorates the ZL1 with the Anniversary Edition 427—an aluminum-block crate engine that mimics the original in spirit, but with design upgrades that make it a street-friendly option for COPO Camaro tribute projects, pro-touring street machines and ultimate-performance “Shark” Corvettes. Our modern aluminum cylinder block has strength-enhancing design features, screw-in galley plugs and more. We’ve also elected to use a hydraulic roller camshaft, making for smoother street operation and greatly reduced maintenance. A 10.1:1 compression ratio allows the Anniversary Edition 427 to drink from today’s gas pumps, too.

To that, we add an all-forged reciprocating assembly for maximum durability, a roller camshaft and a set of tried-andtrue rectangular-port iron cylinder heads. Your 454 HO crate engine package is delivered with a water pump, balancer, 14-inch flexplate and aluminum intake manifold. Add a carburetor, ignition system and starter, and your budget Big-Block will be ready to roar. They’re all available from your nearest GM Performance Parts dealer.

We picked up an additional 15 horsepower while maintaining an incredible 500 lb-ft of torque. The lightweight aluminum heads also help save weight on the nose of a Camaro, Nova or other street/strip machine. The ZZ454/440 uses our new cylinder block casting that offers greater strength and performance (see page 230 for details), while the aluminum heads use smaller, 110cc combustion chambers to boost compression to 9.6:1 (up from 8.5:1 on the 454 HO). We then match the airflow capability with a high-lift, hydraulic roller camshaft that delivers great idle quality and requires no periodic lash adjustments. Our crate engine package delivers the ZZ454/440 assembled with a water pump, balancer, aluminum intake manifold and a 14-inch flexplate.

Our big-torque HT502 crate engine has more pull than a tugboat with a stroker motor. Its robust 512-lb-ft rating (at 3300 rpm) means it has the towing power for almost any trailer. In other words, it’ll turn the Rocky Mountains into mole hills. GM never offered a regular-production 502-cubic-inch Big-Block, but the GM Performance Parts HT502 is a popular, economical choice for truck owners seeking to re-power their old, 454-powered truck with greater power and capability. It is uniquely suited to pre-1976 trucks, but is adaptable to a variety of applications. We build the HT502 with large 4.47-inch bores and a 4.00-inch stroke. The crankshaft, rods and pistons are all forged for maximum strength; and they’re installed in a new version of the Big-Block cylinder block. It is updated for greater strength and performance capability. (See page 230 for details.) Deep breathing chores on the highway are the job of iron, oval-port heads, while a conservative 8.75:1 compression ratio ensures pump-gas performance at all altitudes and engine loads. All necessary components are available from GM Performance Parts. So, go ahead. Load up your race car, parts and a weekend’s worth of support equipment. The HT502 will deliver you and your equipment without breaking a sweat. delivers Big torque new Big-Block casting 377 Hp / 512 lB-ft torque INSTALLATION NOTES • Requires the addition of carburetor, intake manifold, water pump, starter, distributor and ignition system • Clutch linkage bosses are now drilled and tapped.

With 450 horsepower and 550 lb-ft of torque, this Big-Block lacks for nothing. More important than how much power the 502 HO makes is where it makes it. Torque hovers just below the 500 lb-ft mark at only 1500 rpm. The torque curve arcs gently above the 500 lb-ft level by 2800 rpm and stays there through 4200 rpm. All that axle-twisting torque is rooted in a stronger, updated four-bolt cylinder block (see page 230 for details) that houses a forged steel crankshaft, forged and shot-peened rods and forged aluminum pistons. In other words, it’s a super-stout assembly that is as durable as it is powerful. The 502 HO comes complete with an aluminum, dual-plane intake, water pump, 14-inch flexplate, balancer and more. You add the carburetor, starter and ignition system. Iron heads keep the 502 HO affordable—and the wide, flat torque curve makes it a winner for your classic Chevy truck, Camaro or Chevelle.

A hydraulic roller camshaft delivers 0.527/0.544-inch lift specs, and aluminum oval-port heads with 2.25-inch/1.88-inch valves serve as the engine’s lungs. The unique Ram Jet fuel injection system stands 11 inches tall at its highest point and consists of a two-piece manifold/plenum assembly, eight injectors, a throttle body, and an updated MEFI 4 controller.

So when you take your new block to your local machine shop for honing, you should consider having this procedure performed with torque plates installed on the deck surfaces. These tools approximate the load and minute distortion on the block that occurs when the cylinder heads are installed. By having the cylinders honed with a torque plate, you’ll ensure better cylinder pressure and reduce the likelihood of leaks. And, if you plan to supercharge, turbocharge or nitrous-feed your Small-Block, torque-plate honing is a must! 1 Siamesed cylinder walls have thicker cylinder wall material with no water between the bores. This allows for a bigger bore; a bigger bore allows for more cubic inches and more power! 136 350 Bowtie Sportsman Block, 2-Piece Rear Main Seal CNC-machined cast-iron competition block +/-0.001" machining tolerances 4-bolt nodular mains, splayed caps on center three mains 3.980" finished bore 4.155" max bore (siamese cylinder bores) Extra smooth gasket surfaces for better seal Tall lifter bores Builder's Tip CNC-machined cast-iron competition block +/-0.001" machining tolerances 4-bolt nodular mains, splayed caps on center 3 mains 3.980" finished bore 4.155" max bore (siamese cylinder bores) Extra smooth gasket surfaces for better seal Tall lifter bores Comes with rear seal adapter 2 4-bolt mains have more material and more fasteners holding the crank in the block (4-bolts per main instead of just 2). 4-bolt mains help maintain the integrity of the block when you drop the hammer!

Pacing the prestigious race is a job for the hare, not the tortoise, so only the Camaro crown jewel—the SS 396 convertible—was deemed worthy. Not just any SS 396 would do, however, as the actual pace car featured a hopped-up version of the 375-hp L78 Big-Block for good measure. Along with the actual pace car and its backup, more than 100 pace car replicas were built, with 81 of them used at the race and 21 built later for Canadian export. While some of these cars were indeed built with the L78 Big-Block, many of the replicas featured the 295-hp 350 Small-Block, and some of the Canadian clones even featured the 325-hp L48 Big-Block. All featured the familiar blue SS striping, color-keyed blue interior and pace car logos.

Save time and worry by replacing tired or damaged cylinder heads with new ones from GM Performance Parts. The Phase 3 Bowtie cylinder head is a true cast-iron performance head that’s designed for off-highway, competition use only. Racers who are required to run a production-style cast-iron cylinder head can obtain optimum performance with this head because it outflows all production cast-iron heads. The Phase 3 casting is extra thick, which allows ample room for port modifications.

These value-priced cast-iron cylinder heads use modified combustion chambers and high velocity port technology to provide improved performance. Vortec cylinder heads significantly outflow non-Vortec service replacement cylinder heads and earlier OEM cast-iron heads. These cylinder heads are ideal for applications up to 350 horsepower, but they require Vortec-specific intake manifolds. 1967 Camaro SS 350 A. 12558060 Cast-iron Vortec Cylinder Head Assembly • • • • • • • • • • • Completely assembled with 1.94"/1.50" valves Uses bare head 12529093 64cc combustion chamber Straight spark plugs No heat risers Requires Vortec-specific intake manifold Camshafts with more than 0.475" lift require machining valve guide bosses and checking valve seal to valve spring retainer clearance Can be machined for 2.02"/1.60" valves Rocker arm studs can be pinned or drilled and tapped to 3/8" Valve spring seat diameter is 1.28" Casting number 10239906 or 12558062 A Cast-iron Vortec Cylinder Head (intake) Phase 3 Cast-iron Bowtie Head (intake) B “Smile When You Call It Detroit Iron,” smirked the ads featuring the first Camaro Super Sport. Right out of the gate, the ’67 Camaro lineup burst onto the ponycar scene with a host of performance options that brought smiles to the faces of performance-car fans across America. At the heart of those options was the ’67 Camaro SS motivated by the immortal 350-cubicinch Small-Block engine—an engine displacement created just for the new Camaro. This head is assembled with the following components: 10241743 Intake Valves 10241744 Valve Spring Retainer 12550909 Exhaust Valves 10212810 Intake Seals 10212811 Valve Springs 12564852 Exhaust Seals There were more than 80 different factory options for the ’67 Camaro, but the 350 SS was the classic combination. Supported by heavy-duty springs and shocks, and fed by a Rochester four-barrel carburetor, the SS 350’s 295-horsepower Small-Block propelled this classic to 15.4-second quarter-mile ETs, as tested by Motor Trend. Test drivers had a hard time putting down all 380 lb-ft of torque from beneath the SS hood. It wouldn’t be the last time tires had trouble handling the output of a Camaro SS. 24503856 Valve Locks A Cast-iron Vortec Cylinder Head (combustion chamber) 146 Buy online at www.gmperformanceparts.com Phase 3 Cast-iron Bowtie Head (combustion chamber) B Additional components required for installation.

This process puts the heads in a sealed vessel where a vacuum is first used to remove room air and any possible contaminants. The vessel is filled with high pressure nitrogen (up to 30,000-psi) and then heated to the required temperature and sustained for a determined amount of time. The cooling process is also a controlled procedure to insure maximum strength and proper heat treat. This extreme high pressure and heat removes almost 100% of the internal porosities that are generated during the casting process. The material integrity, strength and fatigue life increases significantly.

However, it wasn’t until ’68 that the Z/28 came into its own as a full-fledged model with its own exterior badging. Originally created to sneak in under the Sports Car Club of America’s displacement limits of 305 cubic inches for Trans Am racing, the fusion of a 283 crank and a 327 block resulted in the 302-cube combination. The engine featured large-port heads, with 1.94 intake valves and 1.60 exhaust valves actuated by a solidroller camshaft, but was only rated at 290 horsepower. In reality, it made as much as 350 horsepower. With that kind of power and an F41 Heavy Duty suspension to match, Mark Donahue led team Penske to an SCCA manufacturer’s championship in ’68. Despite its road-racing bent, the Z/28 also cleaned up on the quarter-mile, with Stock Eliminator driver Dave Strickler bringing home the championship in his 11-second Grumpy Jenkins-prepped ’68.

Demonstrating the flexibility of the option sheet, the 396 package turned what could be a sports car into a no-holds-barred muscle car. That stoplight bully could eventually be had with 350, 375, or aluminum-headed, 375-hp 396-cubic-inch Big-Blocks, with the latter L89 engine option being the rarest, with only 272 examples built. C Cylinder Head Nut Kit 3911068 10134358 Instantly identifiable by its unique, faux-vented hood and massive SS grille emblem, the SS 396 was actually more affordable than the high-revving Z/28, and thus more popular. It didn’t hurt that the 375-horse monsters were capable of low 14-second ETs. Sales materials of the day extolled the ’68 Camaros as “husky performers” for the “fun crowd,” and the SS 396 certainly packed as much fun as a Camaro could without intervention from COPO-meddling dealers!

B Short Aluminum Valve Covers Polished Aluminum Valve Covers, Center Bolt Design E By ’69 the Camaro was on a roll, and the factory kept the excitement pumping with aggressive new styling that cemented its legacy as the quintessential Camaro look—a look that unquestionably influenced the new, 2010 Camaro. The long-standing Rally Sport option came with an aggressive grille, squared body panels and multi-section taillights found on all ’69 models, but stood out with its flat-black grille package and slotted, see-through headlight covers that could be opened by more durable vacuum actuation. (The covers were see-through just in case they wouldn’t open.) As it was from its inception, the Rally Sport appearance package was open to just about anything, as it could be combined with more performance-oriented packages like the Z/28 or Super Sport, so it wasn’t uncommon for RS/SS Camaros to prowl the streets with the best of both worlds. Similarly, the 2010 Camaro offers an RS package with unique grille and headlamp treatment—but instead of hidden lamps, they’re hightech, high-intensity discharge lamps.

B Circle Track Valve Covers, Center Bolt Design A legend in its own time and one of the most valuable muscle cars on the market today, the infamous ZL-1 Camaros of 1969 were the Frankenstein monsters of Detroit’s golden age. Chevy dealer Fred Gibb Chevrolet utilized the legendary Central Office Production Order system, worked the system and signed up for 50 Camaros with the ZL-1 427 racing engine—a combination not officially offered by Chevrolet. Chrome Bolt Kit, Center Bolt Design G Created with drag racing in mind, it could be ordered with few or many options, including a heavy-duty Rock Crusher four-speed transmission or even the Rally Sport appearance package. The heart of the car was the allaluminum, 103-octane-swilling 427-inch ZL-1 Big-Block. It was rated at 430 horsepower and 450 lb-ft of torque, but engine dyno testing revealed the truth was somewhere in the 500-horsepower range. Valve Covers: additional required components The spirit of the ZL-1 lives on in our all-aluminum Anniversary 427 limited-production crate engine.

Part Number 12556307 Crankshaft, Forged Steel (used in late-style ZZ4 engine; not shown) Chevy small-block v-8 A crankshaft is that massive piece of convoluted steel that holds the whole engine together. An engine is essentially a pump, and without a strong crankshaft, the pump won’t work. GM Performance Parts puts the same top-quality engineering and manufacturing processes into its crankshafts as it does with all its parts. These crankshafts are the same ones used in GM Performance Parts crate engines. The crankshafts are available in cast-iron and forged steel. Forged crankshafts should be used for higher-horsepower applications. Compressing the air/fuel mixture and dealing with the explosive forces inside an engine’s cylinders isn’t a job for weak parts. That’s why GM Performance Parts pistons are premium quality and factory-tested to withstand the rigors of high-performance street and competition engines. GM Performance Parts pistons are available in a variety of compression ratios and bore sizes. They’re sold individually, unless otherwise specified, and wrist pins are included.

Balancers are also known as torsional dampeners or harmonic balancers, which is indicative of how they help control unwanted crankshaft vibrations. By controlling vibrations, GM Performance Parts balancers help engines run smoothly, which also extends engine life. At the opposite end of the crankshaft from the balancer are flywheels and flexplates, which connect the engine to either manual (flywheels) or automatic (flexplates) transmissions. GM Performance Parts offers both internally and externally balanced flywheels and flexplates. It is critical you use the correct design for your engine application. NOTE: IMPORTANT! All Chevy Small-Block and Big-Block engines with one-piece crankshaft seal require an externally balanced flywheel or flexplate. NOTE: Can be used with a water pump pulley and belt P/N 9433722 without an idler pulley or alternator.

Although they’re fast and easy, they can release particles that are too small for the oil filter to trap. They can also scratch or gouge the gasket mating surface—especially on aluminum parts­—which can cause an oil leak. The best cleaning method is using a gasket scraper or razor blade, with a little help from a parts cleaner brush.

And that’s just fine—but for a new generation of enthusiasts, LS is the new Small-Block and an ’02 Z28 is their ’69 SS 350. The decade that has passed since the LS engine family was introduced has been nothing short of revolutionary. GM engineers applied the inherent advantages of a cam-in-block engine design—low-end torque, compact dimensions and minimal complexity—to state-of-the-art design and manufacturing techniques, creating a clean-sheet engine family. LS engines are capable of exceptional performance per displacement and greater efficiency than the vintage Small-Block it effectively replaced in production vehicles. From an enthusiast standpoint, the LS series is a godsend. In addition to excellent durability, the platform offers great interchangeability, with literally dozens of combinations enabled by a proliferation of regular-production and high-performance cylinder blocks, cylinder heads, induction systems and all the related components. Forward-thinking enthusiasts and racers who joined the LS family early saw great results; and their experience is driving a new wave of high-performance engine-building. LS engines are adaptable to older vehicles as well as late-models, allowing enthusiasts to retro-fit vintage cars and trucks with thoroughly modern performance. GM Performance Parts recognizes the LS series as the next great chapter in GM’s performance legacy and we’re backing that up with an expanded line of high-performance engines, components and support hardware. From production-based systems to our racing-proven LSX high-performance line, we’re constantly pushing to find the outer edge of LS-engine potential—and we’re not even getting close! 188 189 Chevy LS Series 19165628 LS327/327 5.3 327 327 347 3.780 3.622 Everything you wanted to know about GM’s 21st-century Small-Block, but were afraid to ask! 17801267 LS1 5.7 346 350 365 3.898 3.622 17801268 LS6 5.7 346 405 395 3.898 3.622 19165484 (discontinued) LS2 6.0 364 400 400 4.000 3.622 17802134 (discontinued) LS364/440 6.0 364 440 404 4.000 3.622 12611022 L99 6.2 376 430 424 4.065 3.622 19171224 LS376/480 6.2 376 485 475 4.065 3.622 19171225 LS376/515 6.2 376 515 469 4.065 3.622 19201992 LS3 6.2 376 430 424 4.065 3.622 19211978 LSA 6.2 376 556 551 4.065 3.622 19201990 LS9 6.2 376 638 604 4.065 3.622 19171821 CT525 6.2 376 525 471 4.065 3.622 19165058 LS7 7.0 427 505 470 4.125 4.000 Part Description Number LS heritage LS2 The engine family commonly called the LS Series debuted in 1997. General Motors called it the Gen III Small-Block, with the iron-block versions in trucks and the all-aluminum LS1 version introduced in the then-new C5 Corvette. A year later, the LS1 replaced the LT1 Small-Block in Camaros and Firebirds. The LS1 displaced 5.7 liters, similar to the previous-generation Small-Block, but the cubic-inch measurement differed slightly: 346 for the LS1 versus the traditional 350 cubes. In 2005, the LS2 6.0L (364 cubic inches) engine and the Gen IV design changes debuted. In GM performance vehicles, it was offered in the Corvette, GTO and even the heritage-styled SSR roadster. Its larger displacement brought greater power. The LS2 is one of the most adaptable engines, as LS1, LS6, LS3 and L92 cylinder heads work well on it. In 1999, the Gen III platform spawned the higher-performance LS6 that was standard in the Corvette Z06. In 2005, the Gen IV branch of the LS family was born, differing from the Gen III with cast-in provisions for fuel-saving cylinder deactivation, larger displacements and revised camshaft sensing. The performance versions of the Gen IV include the LS2, LS3, LS7 and LS9 supercharged. GM has continued to refer to its modern V-8 engine family as Gen III and Gen IV, but to the enthusiasts who quickly grasped the tremendous performance potential of the engines, every engine based on the platform is nicknamed “LS.” The range of production engines from the LS platform is wide. On the truck side, iron-block engines have included 4.8L and 5.3L versions, as well as all-aluminum 6.0L and 6.2L premium engines. Car engines include 5.3L, 5.7L, 6.0L, 6.2L and 7.0L displacements–including some configured for front-wheel-drive. Gen III versus Gen IV Despite some significant differences between Gen III and Gen IV cylinder blocks, all LS engines share common traits that include: • • • • • • • 4.40" bore centers (like the original Small-Block) Six-bolt, cross-bolted main bearing caps Center main thrust bearing 9.24" deck height Four-bolt-per-cylinder head bolt pattern 0.842" lifter bores Distributorless, coil-near-plug ignition system The most distinguishing differences between Gen II and Gen IV cylinder blocks are larger bores (on some engines), different camshaft position sensor locations—front timing cover area on Gen IV blocks and top-rear position on Gen III blocks—and, on most Gen IV blocks, cast-in provisions for GM’s Active Fuel Management cylinder deactivation system. There is great interchangeability between all LS engines (including between Gen III and Gen IV versions). Cylinder heads, crankshafts, intake manifolds and more can be mixed and matched—but the devil is in the details. Not every head matches every intake manifold and not every crankshaft works with every engine combination. Will Handzel’s “How to Build High-Performance Chevy LS1/LS6 V-8s”P/N 88958786 is a great reference source that outlines the more specific differences and interchangeability among Gen III-based engines. LS4 LS3/L99 Introduced on the 2008 Corvette, the LS3 brought LS base performance to an unprecedented level: 430 horsepower from 6.2L (376 cubic-inches)—making it the most powerful base Corvette engine in history. The LS3 block not only has larger bores than the LS2, but a strengthened casting to support more powerful 6.2L engines. The LS3 is offered in the Pontiac G8 GXP and is also the standard V-8 engine in the new, 2010 Camaro SS. The L99 version is equipped with GM’s fuel-saving Active Fuel Management cylinder deactivation system and is standard on 2010 Camaro SS models equipped with an automatic transmission. LSA The baby brother to the LS9, this supercharged 6.2L engine is standard in the 2009 Cadillac CTS-V. It is built with several differences when compared to the LS9, including hypereutectic pistons versus the LS9’s forged pistons and a smaller, 1.9L supercharger. The LSA also has a different charge-cooler design on top of the supercharger. Horsepower is rated at 556 in the super-quick Caddy. LS9 The most powerful production engine ever from GM, the LS9 is the 6.2L supercharged and charge-cooled engine of the Corvette ZR1. It is rated at an astonishing 638 horsepower. The LS9 uses the strengthened 6.2L block with stronger, roto-cast cylinder heads and a sixth-generation 2.3L Roots-type supercharger. Like the LS7, it uses a dry-sump oiling system. It is the ultimate production LS engine. It is built by hand at the GM Performance Build Center in Wixom, Mich. LS7 A legend in its own time. The LS7 is the standard engine in the Corvette Z06 and its 7.0L displacement (427 cubic inches) makes it the largest small block engine offered in a production car. Unlike LS1/LS6, LS2 and LS3 engines, the LS7 uses a siamese-bore cylinder block design—required for its big, 4.125-inch bores. Competition-proven heads and lightweight components, such as titanium rods and intake valves, make the LS7 a street-tuned racing engine, with 505 horsepower. LS7 engines are built by hand at the GM Performance Build Center in Wixom, Mich. Although performance car engines have typically carried “LS” designations, truck engines built on this platform have been dubbed Vortec. They are generally distinguished by iron cylinder blocks and smaller displacements than car engines. Interestingly, a 5.7L Vortec “LS” engine has never been offered. Here’s a quick rundown of the previous and current-production LS truck engines: • LS1/LS6 • 190 • • 4.8L—The smallest-displacement LS engine (293 cubic-inches); it uses an iron block with 3.78-inch bores and aluminum heads. 5.3L—The most common LS truck engine, it uses the same iron block with 3.78-inch bores as the 4.8L, but with a larger, 3.62-inch stroke crankshaft (327 cubic inches). Later versions are equipped for Active Fuel Management. Manufactured with iron and aluminum cylinder blocks. 6.0L—Used primarily in ¾-ton and one-ton trucks, the 6.0L (364 cubicinches) uses an iron block (LY6) or aluminum block (L76) and aluminum heads, with provisions for Active Fuel Management; some equipped with variable valve timing. 6.2L—Commonly referred to by its L92 engine code, the 6.2L (376 cubic-inches) engine uses an aluminum block and heads, and incorporates advanced technology including variable valve timing. The L92 is used primarily as a high-performance engine for the Cadillac Escalade and GMC Yukon Denali. Buy online at www.gmperformanceparts.com HP Torque Bore Stroke Non-production cylinder blocks Crankshafts C5R: Developed for the factory-backed Corvette racing program, the C5R cylinder block has been manufactured in comparatively small quantities since 2000. They are manufactured with a unique aluminum alloy for greater strength and undergo a variety of specialized machining and inspection processes, including “hipping” to increase strength and X-raying that ensures against unacceptable porosity. A siamese bore design with 4.117-inch finished bores enables 7.0L (427 cubic-inch) displacements. The C5R uses billet steel main caps with premium, 4340 fasteners. Racing-quality head studs are also included. All LS series heads will work with the C5R block, but maximum performance depends on maximum airflow. Generally, LS crankshafts are similar in design, with identical 2.10-inch rod and 2.65-inch main journal sizes and a common rear main seal. All production LS engines use iron crankshafts except the LS7, LS9 and LSA; they use forged steel cranks (4.00-inch stroke on the LS7; 3.62-inch stroke on the LS9 and LSA). LSX Bowtie Block (standard and tall-deck): Introduced in 2007, the LSX Bowtie Block is a durable and affordable cast-iron casting that was designed to support extreme high-performance combinations, including provisions for six-bolts-percylinder head fastening. It has a siamese bore design with 3.99" bores that must be finished to 4.00 inches or larger—with a 4.25-inch maximum bore. Maximum stroke can reach 4.25 inches, but rotating assembly interference on the cylinder must be taken into account for strokes greater than 4.125 inches; heavy metal is required for crankshaft balancing of larger-stroke combinations. Standard versions feature decks 0.020-inch taller than LS production blocks, with the tall-deck version manufactured with a 9.70-inch semi-finished deck height. The oiling system is a true priority-main system and all LS Small-Block heads work with the engine. Gen III and Gen IV Vortec truck engines Perhaps the most unique application of the LS engine in a car, the LS4 is a 5.3L version used in the front-wheel-drive Chevrolet Impala SS and Pontiac Grand Prix GXP. The LS4 has an aluminum block and unique low-profile front-end accessory system, including a “flattened” water pump to accommodate the transverse mounting position within the Impala and Grand Prix. It is rated at 303 horsepower and 323 lb-ft of torque. LS1 5.7L (346-cu-in) engines were produced between the 1997 and 2004 model years in the United States (Corvette, Camaro, Firebird and GTO) and stretching into 2005 in other markets (primarily Australia). The LS6 was introduced in 2001 in the Corvette Z06 and was manufactured through 2005, when it also was found in the Cadillac CTS-V. The LS1 and LS6 share a 5.7L displacement, but the LS6 production engine uses a unique block casting with enhanced strength, greater bay-to-bay breathing capability and other minor differences. The heads, intake manifolds and camshaft also are unique LS6 parts. Liters CID Chevy Ls Series The LS Engine Family Tree Gen iii/IV Small-Block crate engines Connecting Rods LS connecting rods are very similar and mostly interchangeable. Most are made of powdered metal, while the LS7 and LS9 rods are forged titanium. Rods lengths are similar, too, at 6.098-inch for 5.3L, 5.7L, 6.0L and 6.2L engines. The 4.8L engine uses 6.275-inch rods and the LS7 uses 6.067-inch rods. Since 2006, LS rods use bushed small ends. Also, LS6 rods bolts (P/N 11600158) offer a strength-enhancing upgrade to pre-2000 engines. Finally, the LS7 and LS9 rods have a slightly different size than other LS rods, requiring a unique bearing (P/N 89017811). The crankshaft sensing function of the distributorless ignition system depends on reading the toothed reluctor wheel on the crankshaft. Early LS engines mostly used 24-tooth wheels and upgraded a few years ago to 58-tooth (also known as 58X) wheels. When building an LS engine, it is imperative that the correct reluctor wheel is used with the compatible crankshaft position sensor and ignition controller. The crankshafts are mostly interchangeable, but the snouts on LS7 and LS9 crankshafts are approximately one-inch longer to accommodate their two-stage oil pumps that work with the engines’ dry-sump oiling systems. These forged crankshafts can be used on wet-sump engines by using a few specific components and/or modifications (see page 218). The easiest way to put a forged stroker crankshaft in your LS engine is using GM Performance Parts’ new LSX crankshafts, which are available in four stroke sizes up to 4.125 inches. They feature the standard-length snout and can be used without modification on most engines. LS7 and LS9 crankshafts can be used, but require special components and/or modifications to their snouts to accommodate standard, wet-sump oiling systems. SPECIAL NOTE ABOUT CRANKSHAFT BOLT PATTERNS All Pre-2009 crankshafts utilize a 6-bolt flywheel/flexplate bolt pattern. Starting in 2009, the LSA utilizes an 8-bolt pattern, and the LS9 utilizes a unique 9-bolt pattern. All LSX high performance crankshafts utilize the 8-bolt pattern common to the LSA. Pistons The LS9 is the only production LS engine with forged aluminum pistons; all the other engines use hypereutectic (cast) aluminum alloy pistons—varied mostly by diameter to accommodate various bore sizes. LS cast pistons shouldn’t be used on applications greater than approximately 550 horsepower. The LS7 piston’s inner bracing and larger pin diameter require the use of the matching LS7 connecting rod. The same is true for LS9 pistons; they require the use of LS9 connecting rods.

The port sizes and shapes include: Each LS cylinder head has specific valve sizes, locations and valve angles. Here’s an overview of them: Cathedral-port heads Designed for smaller-displacement engines, these heads have the smallest valves; 2.00-inch intake and 1.50-inch exhaust, and they’re held at a 15-degree angle. They also have the closest valve spacing, which limits the maximum valve size. LS6 valves include lightweight hollow-stem intake and sodium-filled exhaust parts; all others in this family feature solid-stem construction. Rectangular port—L92 style L92 heads Similar to the LS7 design, but the ports are a little taller and a little narrower (photo B). They flow more than cathedral-port heads, but not as much as LS7 heads. In addition to the L92 6.2L engines, this port shape is also used on LS3 engines and some 6.0L truck engines, as well as the Corvette ZR1’s LS9 and Cadillac CTS-V’s LSA supercharged engines. Intake manifold bolt patterns are unique to this port design. LS7 Intake Port and Bolt Pattern C A Cathedral Intake Port and Bolt Pattern Rectangular port—LS7 style Similar in design to the LS7 head, the L92 heads don’t flow quite as much and the valves are correspondingly smaller: 2.165-inch on the intake side and 1.59 inch on the exhaust side. They are held at a 15-degree angle and also require offset rocker arms. These heads/valves require at least a 4.00-inch bore, but work best on an engine with a 4.06-inch bore. Valve-to-piston clearance much be checked when using them on an engine originally equipped with cathedral-port heads. LS7 heads The third LS intake runner design debuted on the Corvette Z06’s LS7 engine (photo C). This rectangular design supports the straight-through airflow design of the heads. The LS7 head is the highest flowing production head GM has ever made, to date. They feature 270cc intake ports and the ports and combustion chambers are CNC-ported from the factory. Use only with LS7-style intake manifolds. Using LS series’ largest production valves—2.20-inch on the intake side and 1.61-inch on the exhaust—the LS7 heads offer tremendous airflow, but they require an engine with no less than 4.10-inch bores. The intake valves are made of titanium and the exhaust valves are sodium-filled; they are held at a 12-degree angle. That and their large size require offset rocker arms on the intake side. Valve-to-piston clearance must be checked when using these heads with pistons not designed for the LS7 engine. C5R heads These heads pioneered the rectangular-port design, but because they are designed for professional finishing, their final shape and size depends on whoever is performing the porting. The port shape and bolt pattern are unique. C5R Designed for engines with at least 4.125-inch bores, these heads can accommodate 2.20-inch intake and 1.65-inch exhaust valves; they are held at an 11-degree angle and their spacing is unique. When using on an engine not originally designed for C5R pistons, valve-to-piston clearance must be checked. LSX-CT and LSX-DR ports CT and DR ports are derived from the C5R rectangular shape, but raised 10mm over standard C5R design, and the bolt pattern is spread for more varied port configurations (photo D). The CT port is suitable for sprint car applications both with and without alcohol down nozzles, while the DR targets larger displacements and/or higher rpm in drag racing applications. LSX-CT and LSX-DR CT and DR are in-line heads, with a valve angle of 11 degrees. The CT head was designed specifically for 410 CID sprint car applications, with 2.20-inch intake and 1.61-inch exhaust valve sizes, with valve placement modified and optimized for 4.125-inch bores. DR heads were designed for 410-plus CID, high rpm drag racing applications. Valve placement was spread from the CT to allow up to 2.28-inch and 1.62-inch valves.

All production engines use investment-cast rockers with roller trunnions. They attach to a bolt-down mounting bracket (except for LS7 and LS9 applications that have machined pedestals) that makes installation fast and easy. All production engines feature 1.7-ratio rockers, except the LS7, which uses 1.8-ratio rockers. Rockers are specific to their cylinder head families. Here’s a look at the various applications: Because of their comparatively small bores—3.89 inches—LS1 and LS6 engines can only use LS1, LS6 and LS2 heads. Using heads designed for larger engines will cause valve-to-block interference. The larger, 4.00-inch bore of the LS2 enables it to use LS1/LS6 heads, as well as L92-style heads (including LS3, LS9 and LSA). The 6.2L engines (LS3, L92, etc.) can use all production heads except for the LS7, while the 7.0L LS7 and C5R blocks can use any LS Series head. LS7 blocks should be matched with heads designed for at least 4.10" bores; 4.125-inch bores are preferred. Cathedral-port heads Use interchangeable rockers on the intake and exhaust sides P/N 10214664. (Photo A) Most LS production cylinder blocks share the came cylinder head bolt pattern and the same size head bolts—four 11mm bolts per cylinder (10 in total) and five upper, 8mm bolts. Early LS1 and LS6 engines used different-length 11mm bolts, but engines from 2004 and later use same-length bolts. LS9 engines use stronger, 12mm head bolts. L92 heads Use specific, offset intake rockers P/N 12569167 and non-offset exhaust rockers P/N 10214664. (Photo B) LS7 heads Non-production blocks, such as GM Performance Parts’ LSX block and the C5R, offer the same head-bolt pattern as production blocks. All LS heads will bolt up to them, but care must be taken to select the most compatible heads based on the appropriate bore size. Because of their large bores, heads designed for at least 4.10-inch bores should be used and 4.125-inch bores are preferred, such as the L92/LS3 or LS7 heads otherwise, valve-toblock interference is an issue, as is sufficient cylinder sealing. LS7 Rockers C A LS6 Rockers Use specific, offset intake rockers P/N 12579615 and non-offset exhaust rockers (P/N 12579617). (Photo C) LSX-CT and LSX-DR heads LSX-CT and LSX-DR heads require racing-style shaft mount rocker systems. GMPP offers a 1.85:1-ratio rocker arm kit (P/N 19201808). Includes all necessary hardware. (Photo D) Chevy Ls Series Valvetrain GM Performance Parts’ new LSX cylinder heads use (10) 11mm and (13) 8mm head bolts, or eight more than a regular-production LS head. That’s more than 50-percent more head bolts than production heads, offering a 21-percent increase in total clamping capability and 100-percent more clamping in the 12 o'clock and 6 o'clock positions, right where gaskets leak and blow out in poweradder applications.

A European influence shone through in a longer, heavier, rounder Camaro and the Z/28 was no exception. The latest Z/28 birthed a new engine, too­—the LT-1. Gone was the small, rev-happy 302 and in its place was a 350-cube, 360-horse power plant that propelled the Z/28 to a 14.2-second quarter-mile ET, at more than 100 mph, in Car and Driver’s published test. The engine meant business with 4-bolt mains, 11:1 compression, a high-rise intake, two cam options, and for the first time a Turbo-Hydramatic automatic transmission. In deference to the car’s mission in SCCA racing, it received a standard F-41 heavy-duty suspension—and air conditioning was still unavailable. The modern successor to the LT-1 is the ZZ4 350 crate engine, which pumps out 355 horsepower—only 5 hp shy of the classic engine. 198 * HIP is the acronym for Hot Isostatic Pressure. This process puts the blocks in a sealed vessel where a vacuum is first used to remove room air and any possible contaminants. The vessel is filled with high pressure nitrogen (up to 30,000-psi) and then heated to the required temperature and sustained for a determined amount of time. The cooling process is also a controlled procedure to insure maximum strength and proper heat treat. This extreme high pressure and heat removes almost 100% of the internal porosities that are generated during the casting process. The material integrity, strength and fatigue life increases significantly.

GM Performance Parts delivers those power-building attributes to you with a range of production-style aluminum heads—from the LS6 heads for smaller-displacement engines to LS7 style heads for 427-inch-and-larger combinations, our aluminum heads benefit from General Motors’ extensive research and development program, ensuring maximum airflow without compromises. In fact, many professional builders use our heads as straight bolt-ons, with no further machining. Many of our assembled heads use premium machining and materials, including CNC finishing and porting, along with lightweight, hollow-stem valves, sodium-filled exhaust valves and—on some heads—lightweight titanium intake valves. • • • • • • • • • • Manufactured from 319-T5 aluminum alloy High-efficiency combustion chambers Symmetrical intake and exhaust ports Angled spark plugs (14mm; 5/8" hex; ¾" reach; taper-seat plugs) 15° valve angle (except C5R and LS7) Bolt-down-type rocker arms (except C5R) Center-bolt valve cover hold-downs Fits Gen III and Gen IV Small-Blocks only* • • • • • • • • A LS6 Cylinder Head Assembly (exhaust) CNC-Ported LS2 Cylinder Head Assembly (intake) B A. 12564824 LS6 Cylinder Head Assembly • • • • • • 2.00" hollow stem intake, and 1.55" sodium-filled exhaust valves .570" max valve lift 210cc cathedral port intake ports 70cc D-shaped exhaust ports 65cc combustion chambers Bare head P/N 12615363 available separately * GM Performance Parts heads will not fit 4.8L and 5.3L engines due to their smaller bore sizes. 204 Lower cost alternative to the LS6 head 2.00" solid stem intake, and 1.55" solid stem exhaust valves .570" max valve lift 210cc cathedral-port intake ports 70cc D-shaped exhaust ports 65cc combustion chambers Bare head P/N 12615363 available separately Upgrade the valves to LS6 hollow stem valves with P/N 17801930 B. 88958765 CNC-Ported LS2 Cylinder Head Assembly Aluminum LS Family Head Technical Notes: • • • • CNC-ported aluminum performance head 2.00" hollow stem intake, and 1.55" sodium-filled exhaust valves .570" max valve lift 250cc CNC’d cathedral-port intake ports 85cc CNC’d D-shaped exhaust ports 65cc CNC’d combustion chambers Chevy Ls Series CNC-ported aluminum performance head 2.00" hollow stem intake, and 1.55" sodium-filled exhaust valves .570" max valve lift 250cc CNC’d cathedral-port intake ports 85cc CNC’d D-shaped exhaust ports 65cc CNC’d combustion chambers CNC-ported aluminum performance head Lower cost alternative to the CNC LS6 head 2.00" solid stem intake, and 1.55" solid stem exhaust valves .570" max valve lift 250cc CNC’d cathedral-port intake ports 85cc CNC’d D-shaped exhaust ports 65cc CNC’d combustion chambers Upgrade the valves to LS6 hollow stem valves with P/N 17801930 Heads P/N 12576063 and P/N 88958765 are assembled with the following components: 12563063 Intake Valves 10166344 Valve Spring Retainers 12563064 Exhaust Valves 12482063 Intake Valve Stem Seals 12586484 Valve Springs 12482062 Exhaust Valve Stem Seals 10166345 Valve Locks LS2 and LS6 Head Flow Data: A LS6 Cylinder Head Assembly (intake) Buy online at www.gmperformanceparts.com CNC-Ported LS2 Cylinder Head Assembly (combustion chamber) B Lift 0.200" 0.300" 0.400" 0.500" Stock intake 136 195 237 260 260 Stock exhaust 104 135 157 169 180 0.600" CNC intake 147 215 262 290 307 CNC exhaust 111 155 198 210 218 *G  M Performance Parts heads will not fit 4.8L and 5.3L engines due to their smaller bore sizes.

NOTE: LSX Ignition Controller P/N 19171130 is required for carbureted applications. Just on the eve of the 1970s gas crunch, the V-8 option dominated Camaro production. 1972 was the final year a Big-Block was offered in a Camaro. A scant 970 Big-Blockequipped Camaro SS models were sold that year, as Big-Blocks meant big insurance surcharges after years of unbridled muscle car mayhem.

Its 350-cube Small-Block lost compression due to tighter emissions regulations, and subsequently only produced 255 horsepower, but still out-muscled its Big-Block brethren. Road & Track tested an automatic-equipped version and managed a 15.5-second quarter-mile at 90 mph. NOTE: LSX Ignition Controller P/N 19171130 is required for carbureted applications. Interestingly, GM Performance Parts’ lowest-rated, most inexpensive 350" crate engine, the 350/290 is rated at 290 hp—35 more than the ’72 engine.

A great idea never goes out of style, and the Z28 was a perfect example. After a two-model-year hiatus, the Z28 returned—without a slash—but gone was the emphasis on high-compression, high-rpm engines. The new Z28 was all about handling. It was no surprise the Z apexed again in ’77, as part of the popular Camaro lineup that outsold its pony car rival by a landslide. Header Flange That legend grew as the top race drivers of the day competed in the International Race of Champions in Z28s, with AJ Foyt winning the championship. The street version’s 350-cubic-inch Small-Block picked up 15 horsepower over the standard LM-1 Small-Block, due in large part to a free-flowing exhaust system, resulting in185 horsepower and 280 lb-ft of torque. Car and Driver extracted a 16.3-second quarter mile at 83.1 mph from a 49-state-spec car, as California regulations dinged the Z with a 10-horse penalty and an automatic as the only transmission choice.

It’s the legendary, incomparable high-performance platform for street, strip and more. Building a Big-Block for maximum performance is easier when you’re using GM-engineered, matched components that have been tested on the dyno and on the drag strip. That’s what you get from GM Performance Parts’ comprehensive range of Big-Block parts. We’ve been designing, building and tuning Big-Blocks longer than anyone, so you can trust that our parts will deliver dependable, race-winning performance. Our lineup of Big-Block parts starts with strong, durable cylinder blocks. GMPP recently updated the block design, incorporating strength-enhancing features and the best attributes of both the Mark IV and Gen V designs. We also offer an updated version of the legendary aluminum ZL-1 block casting. Match your new GMPP cylinder block with our premium, forged rotating parts, competition-ready cylinder heads and matched intakes. We offer the fasteners, accessories and other parts you need to finish the engine and get it running in less time. When you’re building the baddest Big-Block, rely on GM Performance Parts for the best parts. Bowtie Sportsman Block 228 229 Chevy Big-Block v-8 The New Big Block Despite the fuel pump mounting pad difference in their castings, the cylinder blocks of the Mark IV and Gen V are based on the same design architecture. There are several other differences—particularly in the water jackets near the deck surfaces—that make some Mark IV and Gen V parts incompatible, including crucial components such as the cylinder head gaskets. GM recently revised the basic Big-Block architecture to commonize the Mark IV and Gen V, creating an all-new cylinder block casting that commonizes the features of both generations. It also incorporates significant updates and strength-enhancing features that make the Big-Block a stronger engine foundation with provisions to support 21st-century performance. Although the basic Big-Block architecture is revised, GM Performance Parts continues to offer two versions, each differentiated by performance and displacement capability. The Bowtie block continues to be the block of maximum performance. GM Performance Parts crate engines use the revised Big-Block design.

In the late 1980s, a new version arrived, designed for marine and fuel-injected applications. The early-style engines are known as Mark IV Big-Blocks, while the later style is referred to as the Gen V (and Gen VI) Big-Block. You can tell them at a glance by checking for a mechanical fuel pump mounting pad. If it has one, it’s a Mark IV. If there’s no fuel pump pad, it’s a Gen V block.

And while camshaft lift is commonly thought of as the primary culprit of valve/piston interference, the overlap period – when the piston nears top-dead center and the intake valve is starting to open and the exhaust valve is closing – brings the valves and piston closest together. So, don’t assume the gross lift specs are all you have to worry about; duration and lobe separation are equally important, making a careful clearance inspection all the more important. • Bowtie blocks were given a distinctive water jacket design to allow up to 4.600" bores. These blocks can be identified by a “B” suffix behind the casting number Additionally, two new core plugs were added to the rear bulkhead. They enhance the manufacturing process at the foundry and help improve overall quality. Also, new “Bowtie” logo and other identifying marks are added to the Bowtie block, distinguishing it from previous generations. 230 Buy online at www.gmperformanceparts.com Buy online at www.gmperformanceparts.com 231 Chevy Big-block v-8 NEW! Deck Height Diagram Bowtie Sportsman Blocks The blocks are CNC-machined, an automated process that guarantees precise tolerances. There are no approximations on these blocks­—they’re exactly right, which is critical to obtaining maximum performance. GM Performance Parts offers more CNCmachined blocks than anyone. The highest-quality materials are used to cast GM Performance Parts Sportsman Bowtie Blocks. They are also available as tall decks, allowing you to make more cubic inches with larger-stroke crankshafts. These blocks can easily be bored and stroked to 500-or-more cubic inches. They can be fitted with one-piece or twopiece crankshaft seals for less chance of oil leaks (one-piece seals) or more aftermarket components attachments (two-piece seals).

In fact, 1979 saw its production exploded to the highest levels ever. More than 280,000 Camaros were sold, and a whopping 84,877 of those were taut, 175-hp Z28s. However, while Z28 revved on, the LT package faded into the rear-view mirror. Replacing the LT was an all-new, upscale Camaro dubbed the Berlinetta. It was a package that put style and comfort ahead of all-out performance. Featuring more brightwork, a custom interior, two wheel options and more, the Berlinetta was a hit—selling more than 67,000 units. More than looks, the Berlinetta be optioned with a 170-hp LM-1 350 Small-Block that was just 5 horses shy of the top-dog Z28.

It is designed for engine builders who want to custom-machine their blocks for specific racing applications. Toward that end, these premium castings have thick deck surfaces, improved oiling, improved coolant flow and splayed 4-bolt steel bearing caps. Everything is secured with premium fasteners. The combination of a GM Performance Parts cast-iron Bowtie Race Block and your unique engine building skills will put you down the track ahead of the competition. GM Performance Parts Big-Block DRCE (Drag Racing Competition Engine) blocks are the foundation of many of the most powerful Pro Stock drag racing engines. The DRCE family of engine blocks was specifically designed with 500-cubic-inch Pro Stock engines in mind. They are the latest evolution of Pro Stock engine design. In order to build optimum performance, the DRCE blocks have bore spacing that allows for the preferable big bore/short-stroke crankshaft combination. The camshaft has been raised and the distributor moved. The big-bore design unshrouds the heads, which means bigger valves can be used. The result is maximized air/fuel mixtures. All DRCE blocks are sold solid, without lifter holes or head bolt holes, so any GM Big-Block cylinder heads may be used. The DRCE blocks are available in either gray iron or compacted graphite (an extremely high-strength material that helps the block combat bore distortion and crank deflection under stress). See chart on page 231 for complete specifications.

Rectangular intake ports are larger in volume and are designed to enhance high-rpm horsepower. These heads are best for vehicles that see frequent drag strip action. Cylinder heads with oval intake ports are smaller in volume and are designed for greater low-rpm torque. Oval port heads are best for street applications where lots of bottom end, off-the-line power is desired.

The runners are purposely left smaller, so there is ample room for custom porting by the engine builder. Bowtie Race Head Technical Notes: • 356-T6 Aluminum • 9/16" thick decks • No heat risers All-new in ’82, the third-generation Camaro reflected its era. It relied heavily on computers for its slippery new design and its first use of factory fuel injection, dubbed Cross-Fire Injection. Featuring an all-new hatchback design with an expansive, compound-curve hatch glass, the ’82 Camaro was modern inside and out, with a space-age interior design and a modern McPherson strut suspension. Not only was the 5.0-liter-Small-Block-powered Z28 the crown jewel of the Camaro lineup, but it reigned supreme over both the automotive world and the Indianapolis 500, as it was selected as both Motor Trend’s Car Of The Year, and the Indianapolis 500’s pace car. Though Motor Trend only managed a 17.13-second quarter-mile at 80.70 mph, the magazine gushed over the Z’s positive attributes, “Besides being good looking, it just may be the best-handling car built in America.” And following the great replica tradition, 6,360 silver and blue Pace Car Z28 copies hit the streets to celebrate. 242 • Will work on Mark IV cylinder block • Heli-coiled 7/16" screw-in rocker stud holes • As-cast intake and exhaust ports 12363425 Bowtie Racing Cylinder Head (not shown) • • • • • • • • A Bowtie Rectangular Port Aluminum Cylinder Head Assembly (combustion chamber) Buy online at www.gmperformanceparts.com Bowtie 572/620 Cylinder Head Assembly (combustion chamber) Aluminum racing head Machined for 2.19"/1.88" valves (+.400" long required) 380cc rectangular intake ports—raised .100" 110cc exhaust port—raised .750", vanes in port floor (“W” port) 115cc “open chamber” combustion chamber Rocker cover rails raised .250" Two additional head bolt holes in valley Pushrod guide plates P/N 3860038 must be ground for clearance B Additional components required for installation.

When races are won by thousandths of a second there’s no room for second-best parts. The GM Performance Parts DRCE aluminum cylinder heads were specifically designed for the DRCE 2 engine block P/N 24502572 and intended for NHRA Drag Racing Pro Stock competition applications.

Thus was born the infamous 1LE option. A DRCE 2 Raw Aluminum Cylinder Head (intake) Born to celebrate the Camaro Z28’s selection as the race car of choice for the International Race of Champions, this race car tribute took the handling of the previous Z28 deeper into the corner. With a lower center of gravity, specially valved springs and shocks, and 16" aluminum wheels with Goodyear Gatorbacks, the IROC Z was good for 0.92g on the skidpad. DRCE 3 Aluminum Cylinder Head Casting (combustion chamber) IROCs weren’t all about the handling though, as the top-dog 305-cube Small-Block pumped out 215 horsepower and 275 lb-ft of torque through a four-speed automatic transmission. If you wanted a manual transmission, you had to step back to a 190-hp carbureted 305. Choosing the fuel-injected automatic combo netted the then-new Tuned Port Injection (TPI), which featured a dual-bore throttle body and long, torque-producing runners. B Cylinder Heads: additional required components From the LT1 engines that followed to the LS7 crate engine found in this catalog, the induction concept pioneered on the TPI lives today. A DRCE 2 Raw Aluminum Cylinder Head (combustion chamber) 244 A best-kept secret when introduced, a 1LE wasn’t a simple order. You had to begin by ordering the G92 Performance Axle, which featured a limited-slip diff. By ordering G92 and no air, you headed full speed into turn one with two-piston PBR brakes, an aluminum driveshaft, a baffled fuel tank and few creature comforts. Only four racers in the know snatched up 1LE Camaros that first year, but the package would continue on for 11 years. It didn’t take long for racers packing the 1LE to dominate the SCCA Escort Endurance Championship in 1989.

Pushrods are that critical link between the camshaft and the rocker arms. These seemingly innocuous parts play a very important role in the combustion process. Two materials are used: 1010 mild steel for high-performance street cars, power boats, and limited competition applications, and 4130 chrome moly steel for maximum-performance racing engines. GM Performance Parts pushrods are case-hardened for use with pushrod guideplates. Pushrods are available in standard and extended lengths. Check the usage chart below to verify proper applications.

It was rated at 275 horsepower. After 24 long years, a new Camaro SS emerged from a cloud of tire smoke. Not only was it the first Super Sport in far too long, but the fourth-gen SS marked a unique alliance between Chevrolet and longtime Camaro tuner SLP. While its prominent hood scoop announced the SS was willing to inhale and combust its competition, there was more to this Super Sport than free-flowing induction. SLP also added 17" Corvette ZR-1 wheels, and custom-valved shocks augmenting a 1LE suspension. Thanks to the induction, the SS was rated at 305 horsepower, and with the addition of an optional exhaust, the SS belted out 315 horses from its new OBD-IIequipped LT1. A number of options were available to the exclusive SS, of which there were only 2,410 built that year. Debuting a year earlier in the Corvette, the “new” LT1 featured an iron block and high-flow aluminum heads, but the real distinction was its reverse-flow cooling system. Banging gears with the six-speed manual, Motor Trend test drivers managed to just miss the 13-second zone with their best quarter-mile effort of 14.0 at 98 mph. The ’93 Z28 also served as the Indy 500 Pace Car— the fourth time the honor was bestowed on the Camaro. The legacy of the LT1 lives on in the higher-performance LT4-based components still available from GM Performance Parts, including the popular LT4 hot cam. 256 Camaro SS F 12-Point Connecting Rod Nut Buy online at www.gmperformanceparts.com Buy online at www.gmperformanceparts.com 257 Chevy Big-Block v-8 Balancers and Pulleys Crankshafts are a critical, central component of any engine. Strength and durability are important traits of a great crankshaft. GM Performance Parts crankshafts are precision-engineered to be both strong and durable. GM Performance Parts understands how catastrophic crankshaft failure can be, so that’s why its crankshafts are manufactured to such exacting specifications and tested to withstand the forces of high-performance engines. These crankshafts are the same tough parts used in GM Performance Parts crate engines. Balancers are relatively small parts that play a big role in helping engines run smoothly. Balancers are also known as torsional dampeners or harmonic balancers, which is indicative of how they help control unwanted crankshaft vibrations. By controlling vibrations, GM Performance Parts balancers help engines run smoothly, which also extends engine life. 14096987 Flywheel (see chart below) 3963524 Crankshaft, Forged Steel (454 and Mark IV 502-cubic-inches, not shown) • • • • Part Engine Outside Technical Notes Number Application Diameter A Crankshaft, Forged Steel (Gen V and Gen VI 502) 3879623 Originally used on 1967-1969 427, ZZ427 and Anniversary Edition 427 8" 10216339 454 and 502 with 4.00"-stroke crank 8" 88962814 572 8" 14096983 Crankshaft, Forged Steel (Gen V and Gen VI 454, not shown) • • Externally balanced Forged 1053 steel crankshaft with one-piece rear main seal • • • • • • • • 14085720 1965-1989 • • • • 3963537 Steel crankshaft with 3.75" stroke for 1991-and-later 427-cubic-inch engines One-piece rear main seal Requires chamfered connecting rods (P/N 19211226 or 88962926) and rod bearings P/N 88961556 Used in ZZ427 and Anniversary Edition 427 engines Internally balanced B. 88961554 Crankshaft, Forged Steel (572-cubic"es) 1979-1990 12.75" 12.75" 3.58" 3.58" 10.4" 10.4" 153 153 3991469 1965-1969 14" 3.58" 11" 168 3993827 1970-1990 14" 3.58" 11" 168 B Crankshaft, Forged Steel 572 Internally balanced Premium 4340 steel forging for 572-cubic-inch engines Use neutral balance dampener and flexplate or flywheel One-piece rear seal NOTE: Must use main bearing P/N 88962212 and rod bearing P/N 88962926. 14061685 Roller Pilot Bearing (not shown) • This internal balance dampener is designed with inner and outer shells.

Of course, the all-aluminum, 305-hp LS1 wasn’t just another Small-Block, but a completely re-engineered masterpiece. Packing 20 more horsepower and 10 more pound-feet of grunt, but weighing in 10-percent lighter than its LT1 predecessor, the LS1 joined the Camaro with more power, better gas mileage and started a performance revolution. The LS engine revolution continues, with the LS1 leading the way for a succession of greater-performing variants, including the LS6, LS2, LS7 and LS3.

Camaro SS AnniversAry G. 12342071 Air Cleaner, Chevrolet-Logo Classic Design • • • “It’s the Camaro you always dreamed of owning,” exclaimed the ’02 Camaro brochure of the Camaro SS. It was any easy car to remember, thanks to a completely unique package featuring red paint, checkered heritage stripes, unique wheels, two-tone interiors, and much more. Only 3,369 SS were ordered with this package (RPO Z4C), with the T-top coupes being slightly more popular than the convertibles.

Of the cammed-up LS1 in the SS, the brochure added that the “resemblance to the Corvette was purely intentional,” and with 325 horse and 350 lb-ft on tap, there was no argument. In fact GM High Tech Performance extracted a 13.579-second quarter mile at 101.91 mph from the heaviest SS available, an automatic convertible, proving the LS1 muscled up in just a few short years and that the modern Small-Block could run with many of its heralded muscle car forefathers.

Building on the success of our Stage 1 Kit, our GM Performance Parts engineers wanted to push the overachieving fourbanger just a little bit more. Stage 2 takes your Cobalt SS or ION Red Line from a stock rating of 205 horsepower all the way up to 245 horsepower. The key to making that power is increasing the boost on the factory supercharger by swapping out the stock blower pulley. Increased boost means more air getting pumped into the high-revving Ecotec, and the increased airflow requires more fuel. That’s why GM high-flow injectors are included in the kit. Together, this Performance Kit will keep your Cobalt/ION Red Line boosted ahead of the competition. NOTE: premium (93-octane) fuel is required for Stage 2.

The Stage 3 kit consists of the following: • Smaller, 76mm supercharger pulley 2-pass intercooler end plate Unique PCM, which includes a calibration for the smaller pulley, an adjustable rev limiter, a 100-octane mode, and a nitrous control algorithm • • • • • Our Stage 3 Kit will take your supercharged Ecotec 2.0L engine to a whole new level of performance. Stage 3 takes horsepower output to 248 horsepower on 93 octane fuel and to 260 horsepower on 100 octane fuel. In addition to the power increase, you’ll also get an adjustable rev limiter and calibration for a 50-shot of nitrous (nitrous kit not included). For best power, we recommend also installing a high-flow exhaust. This PCM is equipped with a user adjustable rev limit from 6750 to 8000 rpm. The rev limit is adjusted by pressing on the throttle pedal with the ignition on and engine off. At about 50 percent throttle, the tachometer will show the current rev limit. Pressing the throttle further will adjust the rev limit in 250 rpm increments. This PCM is also equipped with a control scheme for the equivalent of a 50-horse shot of nitrous. The PCM will automatically provide the proper spark and fuel for nitrous up to 500 rpm below the current selected rev limit when the trigger is activated. Note: The Stage 3 Kit is for off-road use only. The Stage 3 upgrades are meant for off-road use only and are not certified to be emissions-legal. The vehicle’s air conditioning is disabled by the Stage 3 PCM. Note: This kit is an upgrade to Stage 2. It requires the following parts from the Stage 2 Kit: high-flow fuel injectors, pulley adapter hub and serpentine belt.

From appearance upgrades to serious performance modifications, it’s a car designed for personalization. The 2010 Camaro carries that personal quality, with sensuous styling and a long list of features and options. At GM Perfor Performance Parts, we know the factory options still aren’t enough for many owners. Enthusiasts want even greater personalization options; is there a red-blooded Camaro fan who doesn’t want a few extra horses running wild under the hood? We worked with the Camaro’s planners from the moment its production was green-lighted. We designed and developed appearance, convenience and power-enhancing performance 322 upgrades to complement the car as soon as the first production model rolled off the line. All of our Camaro accessories and performance parts were tested and validated to GM production vehicle specifications and manufactured with production-quality materials. That means you’re getting original equipment quality parts with the best fit and finish. Our performance parts are legal in 50 states, too, for worry-free emissions compliance.

That’s why long before it was scheduled to hit the showroom floor, GM Performance Parts designers and engineers were hard at work developing emissions-legal bolt-on components that would accentuate and enhance the factory-delivered horsepower. Following the adage that more air in and more air out equals more horsepower, we developed air box, header and exhaust kits, as well as complementing short-throw shifters for manual-transmission applications. We even designed colorcoordinated engine covers that may not add any direct horsepower, but just might help grab a “Best in Show” trophy at the next car show. Because you’re buying GM Performance Parts components, you can be confident they’ll fit and perform as promised. They're also emissions-legal in 50 states with CARB EO numbers where required. Check out the parts below and build your Camaro to pull away from the crowd! Exhaust Short-Throw Shifter Upgrade the look and sound of your Camaro’s exhaust system with one of our tuned, emissions-legal bolt-on exhaust kits. They deliver a great performance sound and reduced restriction, which promotes increased power—especially when combined with other performance parts. Whether you’re looking for a street-legal sound or a completely off-roading system, GM Performance Parts has got you covered. The exhausts are available with or without ground effects. When ordering the ground effects package, there is no need to include an exhaust tip. Our exhaust kits are designed for simple remove-and-replace installation, for a quick and hassle-free changeover. NOTE: When selecting a kit for SS models, check for specific LS3 (manual transmission) or L99 (automatic transmission) part numbers. A greater feeling of control comes with a precise, quick-acting shifter. GM Performance Parts’ short-throw shifter kits for both V-6 and V-8 models deliver sharper and quicker throws between gears, enabling you to keep the engine’s revs right where you want them for optimal performance. 92206990 We worked with legendary shifter manufacturer Hurst® to develop the kits, so they complement great performance with classic styling.

Low-restriction exhaust headers enable exhaust gases to be carried away from the engine quicker, boosting the engine’s airflow efficiency and overall performance. Our bolt-on header kit is emissions-legal and provides a simple bolt-in replacement for the factory exhaust manifolds. Match them with one of our exhaust kits for even greater performance.
