Intro
The Maserati Bora made its public debut on March 1971 at the Geneva
Auto show. This was the first time that Maserati introduced a midengine model. Lamborghini already had the Miura and DeTomaso the
Mangusta; and it was rumored that Ferrari was also developing a midengine car. The Bora was therefore a logical step for the new Maserati
flagship model.
The objective of this guide is to document via photos details of how
these cars left the factory. As these cars get older, more and more of
their original decals, paint, plating and overall details are lost. My
objective, with the help of other Bora owners with original cars, is to
document these details before they are lost.
This is not a technical document nor intended in providing tips of how
to make your Bora better. Original does not necessarily equate to good;
just that this was the way the Maserati factory built it.
I am in no way presuming to know it all. My comments are based on
observations from my current Bora (#1044) and from about a dozen
other Boras I’ve owned through the years, plus many others I’ve
observed and photographed. Most of my cars have been the USA
version, although two of them were European delivered cars.
This is intended to be a live document. As other Bora owners observe
an original feature not included in this document, I would encourage
them to take a photo and describe what they saw. It is imperative that
only original features be included in this document. I cannot stress this
enough. Many good intentioned restorers improperly paint or plate
components in ways the factory never did. They may look great, but
they are not original and should not be in this document.

Production numbers and engines
Although it is difficult to know exactly the production numbers,
between 1971 and 1978 the most widely accepted numbers are that
564 Boras were produced of which 275 were fitted with the 4.9 liter V8
engine and 289 with the 4.7 liter engine. Most, if not all, of the Boras
destined to the USA had the 4.9 liter engine, while most of the Euro
cars had the 4.7 engine.
While some Maserati models, such as the Indy, had very significant
changes during their production, the Bora had some minor adjustment
but nothing dramatic.
VIN number locations
The VIN is usually found stamped on the chassis in two locations: 1) on
the crossmember located between the engine and the spare wheel 2)
on the inner side of the right headlight bucket. Most people are not
aware on the VIN number stamped next to the headlight bucket
therefore that is a good place to check if you suspect the VIN has in any
way been altered. In addition to the stampings on the chassis there are
several plates that contain the VIN. These plates can be seen in the
plates section of this document.
5
VIN stamped on cross section – 1977 USA
VIN stamped to the left of the right headlight bucket – 1974 USA
6
Engine number
The engine number is stamped on the rear top of the engine. The last 3
or 4 digits of the engine number need to match the last 3 or 4 digits of
the VIN.
This is the original engine for 1977 Bora AM117/49US*1044*
All V8 Maserati engines of this era were designated as either “107” or
“115”. A 107 engine means it has a wet sump, while a 115 is a dry sump
engine. The first Maserati to use this wet sump engine was the tipo 107
Quattroporte and therefore this engine is an AM107. Confused? To me
it would have been clearer if they had simply stamped the VIN of the
chassis to the engine …. but they did not ask for my opinion.
7
Vented vs non-vented hoods
One of the most visible change was the addition of cooling vents on the
front hood. The effectiveness of these vents has been questioned and
some people claim that the vents made matters worse. The change
seems to have appeared sometime in 1973.
Hood without vents (1973 Euro)
8
Hood with vents
With the introduction of the vents the trunk itself was modified:
Trunk of Bora without vents (1972 Euro)
9
Trunk of Bora with vents (1974 USA)
10
Lower front valance vent openings
Many of the early cars without the hood vents also did not have vents
cut out on the lower valance. Later cars had the vents. I have seen at
least one early car with the valance vents. Were these added by a prior
owner?
No lower valance vents on a 1973 USA
No lower valance vents on a 1973 Euro
11
Vents on a 1977 USA
Lower valance vents on a 1973 Euro. Might this have been added by a
prior owner?
12
Hood hinges
Originally the Bora hood was hinged near the firewall. It was discovered
that at high speed travel, if the front latch was to fail, the hood could
(and did on occasions) fly open. To fix this problem, Boras in 1977 had
their hoods hinged in the front.

13

Wheels
While the Ghibli had at least seven different types of wheels, all the
Boras essentially had the same Campagnolo wheel. Originally the wheel
was fitted with a plain hubcap. In 1977 the hubcap was removed, a
trident placed in the center and the lug nuts changed to chrome, since
they were now exposed. This simple change made a significant
difference in the wheel’s appearance. A close look at the wheel from a
1977 reveals that the indentations that hold the hub caps are still
present making this a very inexpensive method to modernize the look
of the wheels.

14
Campagnolo wheel with center trident and chromed lug nuts. Decals
are also different on the early and later wheels. Refer to the decal
section for details.
Bumpers
Perhaps the most dramatic change through the years were the USA
bumpers. The bumpers as conceived by Guigiaro were mostly
decorations. Pretty they were, but when it came to protect the car and
its driver, they were useless. USA regulations in the 1970’s was quickly
changing. In 1974 bumpers were required to protect the vehicle from a
collision at 2.5 mph. For 1975 that number was increased to 5 MPH.
Maserati had to modify the Bora’s bumpers to meet USA regulations if
they wanted to sell cars in the USA, which at that time was its biggest
market.
Elegant Euro bumpers. USA cars never had these bumpers, although
some cars have been converted.

Side and rear markers
Euro and USA cars differ on the location and size of the side markets.
Euro cars had two red markers above the bumper and two front amber
markers in the front fenders. Also, the rear taillights on the Euro cars
are red/amber while the USA cars have red/red taillights

1977 USA front amber side marker

21

22
Steering wheel
Another mandated item was the steering wheel. USA regulations
required the steering wheel to provide some padding as protection in a
collision. The padded steering wheel was first introduced on the Ghibli
in 1970. Most Euro cars had a non-padded steering wheel although I
believe Boras sold in France had the same steering wheel as the USA.

23
Cam covers and heads
The heads and cam covers were always painted in black wrinkle finish.
In most engines the lettering was sanded down as shown in this photo.
I have also seen the lettering painted in black wrinkle, although less
common.
24
Spark plug wires
The spark plug wires have a white plastic band with the cylinder
number identified. A small black rubber boot goes over the bakelite
connector for the spark plug. Around this connector is a rubber insert
that keep debris away from the spark plug hole. This insert is missing on
many cars as they are sometimes misplaced by prior owners and
mechanics.
25
Head light buckets
Early Boras had head light buckets with square corners. Not long into
the production the buckets were modified, and the corners rounded.
Square buckets
More common rounded buckets
26
Seats
While the seats on all Boras were the same the pleats were either flat
or “puffy”. The puffy pleats are like those seen on the Citroen SM. I
have not seen an explanation as to when or why the pleats were
different. It seems to have been a random thing.
1972 Euro with puffy pleats
1977 USA with flat pleats
27
Passenger foot rest
Some Boras had passenger footrests and others did not.
No foot rest – 1974 USA
Passenger foot rest – 1977 USA
28
Stainless steel roof
All Boras came with a stainless-steel roof. This was simply a design
element and has no practical purpose. Damaged stainless-steel roofs
are one of the most difficult things to fix on a Bora as they are no easy
to remove.

29
Side Mirrors
Side mirrors were many times determined by the country to which the
Bora was being sold. While there is no right or wrong mirror in general
the early cars (pre-1975) had chrome or plastic chrome plated mirrors
while the later cars had the black rectangular Vitaloni Tornado mirrors.
The mirrors on the later cars were electric and provided adjustment
with a paddle switch mounted on the door panel.

30
Engine cover
The engine cover changed very little during the Bora’s production
except towards the engine the factory finally realized that placing a
couple of handles on the cover would make it much easier to remove.
1972 Euro without handles
1977 USA with handles
31
Engine compartment paint
The engine compartment on most Boras are painted the match the
exterior. For the 1977 models the engine compartments were all black
and I would say the finish was not as good as the earlier cars. I suspect
the engine compartments were painted black as it would be easier to
hide imperfections, thereby saving some cost.
Painted to match exterior on a 1973 Euro
Black under the engine lid on a gold 1977 USA
32
Glass
The glass on the Bora was made by Saint Gobian and it is date coded.
The number represents the last digit of the year while the letter
represents the month. In this photo we see an “8” for 1978 and “D” for
the month of April. It is interesting to note that on this car a couple of
the glass were manufactured in 1973 which means the factory was
using up old inventory as they were finishing up the last few Boras. This
Bora was the third to last made.
33
Jack
The Battaini jack is located inside the engine compartment and fits into
a bracket and then held with a spring.

35
Spare tire
A full-size Michelin 215/70 x 15 XWX tire was provided with a cover.
The spare tire is above the ZF transaxle.

36
User manuals
The most common Bora user manual has a dark green cover. There was
also a Warranty and Maintenance manual, and usually a manual for the
radio
Manual with tool kit
Warranty manual which in 1977 was shared with the Khamsin. Also, the
radio manual. The grey manual is a USA supplement.
37
Tool kit
Boras were fitted with a tool kit that was very similar to those used on
the Ghibli and Indy. Since the Bora never had knock off wheels only the
French hammer was provided.
38
Dash warning lights
Pre-1977 Boras has either two or three non-labeled warning lights to
indicate if the LHM pressure was too low, hand brake was on and if the
brake pads were worn too much. Of course, it was up to the owner to
figure out what each of these lights meant. The 1977 model had the
warning lights labeled and relocated. When the LHM pressure is too
low the light labeled “Stop Brake Failure” blinks and buzzer sounds.

was moved to the left and labeled. The hazard switch was changed.
41
Carpet and heel pads
These photos show a typical original Bora carpet. You can see how the
piping was stitched and how the heel pad was cut to accommodate for
the passenger foot rest.

has small ribs. This heel pad is difference to that used on prior
Maserati.
The carpet inside the front trunk area and the engine compartment is
grey with black fibers on most Boras. On some cars the carpet is black.

Headliner
The headliner is ribbed and has an indentation for the sun visors.

47
Radios
Several different radios were available for the Bora, but most were
Baupunkt. Most had cassette tapes and provided the option to record
with a microphone.
1974 USA
1977 USA, the microphone is in the additional box located under the
dash
48
This gooseneck radio from a 1973 USA was the top of the line and a
very expensive option. Notice the microphone located on the left lower
side of the cabin. The microphone has a switch to pause recording. I
can’t imagine anyone really dictating a letter while motoring at speed
and trying to shift gears at the same time!
49
Antenna (aerial)
The Bora’s antenna in unique in that when in its recessed position the
top of the antenna is flushed with the body and there is no chrome
surrounding as typically found on other cars of this era. The Iso Grifo
has a similar antenna design.
It is interesting to note that the Merak, even though it shares the front
end with the Bora, did not have the same antenna design.
The antenna is raised and lowered with a dash mounted switch.
50
Luggage
The Bora sales manual shows two pieces of luggage in the front trunk.
The luggage appears to be the same as was available for the Ghibli. I
reproduced the luggage for my Ghibli and found that the dimensions
were perfect for the Bora and had a couple of luggage pieces made for
my Bora to match the interior color. I would appreciate a photo of
original Bora luggage for this document.

51
Gas struts
There are two rear gas struts for the engine cover and either one or
two struts for the front hood. Cars with the front hood hinged near the
firewall usually have one strut while those hinged in the front have two
struts.

1977 USA - Carrozzeria plate is most likely a unique number assigned to
the body. I do not know the purpose of the Autovettura number.
Emissions plates (USA)
1977 USA – Emission information plate. This is a USA only plate and
would be different for every year. This plate indicated the car meets the
emissions regulations for 1977; even though the car was completed in
September of 1978.

70
Assembly markings
During the manufacturing and assembly of the Bora several markings
were put on the car to indicate that the work has been completed.
Although I can only speculate on the significance of the markings they
clearly had some significance during the assembly process. This is just a
sampling of the some of the markings. If you find an original assembly
marking on your Bora, please photograph it and indicate its location.
Head “red dot” marking
Towards the front of each head, right on the middle of the valley, there
should be a painted red circle. Perhaps this was put on after the valves
had been adjusted.
Red dot on a 1977 USA
71
Brake caliper markings
The Bora brake calipers were plated, and a blue marking applied. Not
sure of its purpose but perhaps to indicate that the calipers had been
pressure tested.
Front caliper – 1977 USA
Rear caliper – 1977 USA
72
Bosch ignition amplifier marking
There was a tiny red dot put on the amplifier, most likely after it had
been tested to be working correctly.
Chalk markings
Sometimes removable panels were hand marked with the last digits of
the VIN to identify to which car the part belongs. I found this part on
my car (#1044) which was intended to go to car #1048. Either someone
picked the wrong part during assembly or they were in a rush to get my
car finished and a part was “borrowed” from another one that was
being assembled at the same time.
73
Paint colors and code
I obtained the list on the following page from long time Maserati
factory historian Ermanno Cozza. This list is in no way complete but
includes most of the most common Bora colors. The color of my Bora,
Oro Longchamp, is not on this list.
