| In
1951 a group of Harley Earl's "Special Projects" crew began work
on a GM sports car. Bob McLean designed a general layout for the car.. The
project was code named, "Opel".
William Durant, the founder of GM, said a
wallpaper pattern he saw in a Paris hotel in 1908 inspired the bow tie
logo. Supposedly, he ripped off a small piece of it and brought it back to
Detroit.
The man who named the Corvette was Myron
Scott... Then Chevrolet's Chief photographer.
The Jaguar XK120 is believed to have been
the inspiration for the first Corvette.
The Corvette was the first and last car
with a "Wrap-Around" windshield.
Corvette was not the first to be made with
a fiberglass body, but it was the first to be built by a company the size
of Chevrolet.
Corvettes have been assembled in three
different cities. Flint, St. Louis, and Bowling Green.
"Turbojet" as first used on
Corvette engine air cleaners with a horsepower rating of greater than
390hp.
1953
to 1962
The original front emblem and horn button
on the "Autorama" Corvette featured crossed American and
Checkered flags. It was discovered that using an American flag on a
product trade mark was against the law and the emblem was changed before
the New York Motorama.
The hash faces up on front fender molding
of the "Autorama", 1953 Corvette and on the actual production
car it faces down.
On Tuesday, June 30, 1953 Corvette #1
Serial Number E53F001001 rolled of the assembly line, and Corvette
production began.
Want the rarest Corvette ?- In 1953 the
first two Corvettes, VIN Numbers 1 and 2 were said to have been destroyed,
but no records prove that fact, and there are no witnesses to the
destruction.
The first Corvettes were actually
"rolled" off the assembly line. Chevrolet was not prepared for
grounding to a fiberglass body; the cars would not start.
The first five Corvettes to come off the
assembly line did not have an outside rear view mirror.
The only thing really new on the 1953
Corvette was the fiberglass body. Everything else was directly off the
Chevrolet parts shelf. Because of this, the first Corvette was essentially
a regular 1952 Chevrolet that looked like a million dollars!
Of the 314 Corvettes hand built in 1953
only 183 were sold because of "average" performance at such a
high price, $3513 the Jaguar Xk120 sold for $3345, $168 less than the
Corvette.
There are 13 vertical bars or
"teeth" are in the grill of 1956 Corvettes.
One of the few ways to differentiate
between a 1956 and 1957 Corvette without opening the hood is to look at
the inside rear view mirror. On the 1956 model, it adjusts with a
thumbscrew, on the 1957 adjustment requires a wrench to loosen the
locknut.
The "Polo White" color was last
used in 1957.
1957 was the first year a limited slip
differential was offered as an option.
1958 was the LAST year of the tach with the
"cumulative engine revolution counter" which first appeared in
the 1953 Corvette. In 1958 the tach was used on 230, 245, and 250 hp cars
and NOT on the 270 and 290 hp cars. The Part number is #1548631 for 1958.
Optional engines in 1956 had nine fin alloy
valve covers, 1957 had seven or nine fin alloy valve covers, and the 1958
had seven fin alloy covers on optional engines.
Before 1958, the only Acrylic lacquer paint
used was on the "Inca Silver" Vettes.
Sun visors became a Corvette option in
1959.
Nylon belted tires first became available
on the 1960 Corvette, prior to 1960 only cotton was offered.
The 1961 Corvette was the last year to
feature "Wide Whitewall" tires.
The 1961 Corvette was the first to not have
the "round" nose emblem.
In 1961, the big grill teeth disappeared
forever, replaced by a fine mesh.
1962 Was the last of the solid rear axle
Corvettes and the last year for the power top on the roadster.
1963
to 1967
The earliest serial number air conditioned
Sting Ray has a production build date in October, about 6 months before
the rest of the AC cars. The reason? The owner was a GM executive and the
car returned to Chevrolet for refitting with AC.
An error was made in creating the roof
panel mold in 1963, using the wrong side of the dimensions, such that all
roof panels were too small. This left a gap seen in the door pillar above
the door latch in all but a few 1963's to 1967. The ones where it is not
found were cosmetically covered up with body filler.
Power steering was first available in the
1963 Corvette.
Bill Mitchell and Zora Arkus-Duntov argued
over the "Split" rear window for the new Corvette. Bill Mitchell
won out for the 1963 Model, but it was removed for 1964 never to be seen
again.
The 1963 Grand Sports, while originally
looking much like the production coupes, had no body parts in common. The
fiberglass body panels were roughly half the thickness of production
panels to save weight.
The 1963 Grand Sports originally were
released without fender flares, using the stock look. However, they were
wider to allow a wider tire 8.25x15 rather than the stock 6.70x15 tire.
Only the driver's side vent on the 1964
Corvette is functional.
The first major tire size change in
Corvette history occurred in 1965. Tire size changed from 6.70x15 to
7.75x15
While the 427 was developed first, the 396
went into the Corvette, Chevrolet, and Chevelle in 1965 due to a GM policy
restricting them to less than 400 cubic inches.
The 396ci 425hp engine lasted only one year
1965.
1965 was the first year to have two
separate hoods - the smooth small block hood and the bulge of the big
block hood.
The 1966 Corvette was not eligible in SCCA
Trans Am, due to the upper limit of 5.0 liter on engine displacement.
Chevy's only eligible car was the Corvair.
1967 was the first year to have three
hoods: the small block hood, the big block hood, and the L-88 hood, even
though externally the L-88 looked like the regular big block hood.
In late February and early March, 1967,
some small blocks received the big block hood due to an industrial
accident with the small block hood mold. These were not given the hood
stripe.
The "GM Mark of Excellence"
sticker appeared in one year only- 1967.
Federal law mandated the removal of
spinners from wheels in 1967, so the knock off wheel of 1963-66 was
replaced with a bolt on wheel.
1967 was the first year "Vinyl"
was offered as an optional exterior covering for the hardtop.
The '67 model was the first to have the
"tank sticker", or the build sheet, attached to the gas tank.
The maximum install fuel tank capacity was
offered in the Corvette from 1963 to 1967, 36 gallons.
An option was offered in 1967 that lasted
for only three production years.. A speed warning indicator.
The '67 LeMans Racer was "DRIVEN"
to the track from the airport (in place of being trailered) was because
the trailer was chuck full of parts!
1968
to 1982
Pontiac almost beat Chevrolet to the Coke
bottle design body, with their 1965 Banshee, a two seater convertible
sports car that would have been hefty competition for the Corvette. GM
stopped it, and then Pontiac president John DeLorean later became
president of Chevrolet.
T-top does not refer to the shape of the
roof, but rather it is short for Targa Top. The original design was a pure
Targa but body flex demanded the center bar, discovered late in the
design.
Due to policy changes in Chevrolet,
Corvette was treated like all other car lines for the first time, and
quality dropped drastically. With bad publicity in most magazines, policy
was re-thought and Chevrolet quickly restored independence and quality to
Corvette within a few months, but all 1968s carry the stigma of being
"the worse quality" of all Corvettes.
All big block manifolds were redesigned to
actually sink into the lifter valley as the hood clearance was less than
in '67 and back. As such, a 1965 to 1967 big block intake manifold won't
fit in a 1968 or newer Corvette with a stock hood and air cleaner.
The exception to the above was the L-88. It
retained the high rise manifold and also received a special hood, which
was externally different this time.
Emission control equipment was installed on
the first 1968's in the fall of 1967 even though the federal law required
it only as of January 1, 1968.
1968 was the first year AM/FM stereo was
offered as an option.
1968-1972 the coupe's rearwindow was
removeable for more of a true convertible experience
The Sting Ray name was not used on the 1968
Corvette, but returned in 1969… Spelled Stingray.
Corvette had its first all aluminum engine
in 1969 as the ZL-1. It was not the first GM automobile to do so, beaten
by the Corvair in 1960 and the Buick 215 V8.
In 1969, the ignition lock was moved from
the dash to the steering column. It would remain there until 1997 when it
was returned to the dash.
The LS7 engine option, which was never
installed in the 1970 Corvette was $3000.
No Corvettes were painted Black at the
factory from 1970 to 1976.
The only outside difference between the
1971 and a 1972 Corvette is the appearance of the amber front turn signals
and vertical chroming on the egg-crate grills both on the 1972 - that's
it. Minor stuff most people miss.
1972 was the only year for Corvette
"Big Block" engines in the 1968 to 1972 range to have no horse
power sticker on the air cleaner lid.
"Pewter Silver" was only offered
as an exterior color in 1972.
The 1970 - 1972 Corvettes were the last to
feature chrome bumpers front and rear. In 1973, the front bumper changed
to body-colored flexible plastic. In 1974 the rear bumper followed suit.
In 1973, aluminum wheels were again
available as an option, but the same problem that plagued the 1963
aluminum wheels, the inability to hold air, kept these out of the hands of
customers until 1976.
The rear view mirror in the 1974 Corvette
was increased to a width of 10".
The last true dual exhaust was installed in
1974, after that, everything went through a catalytic converter.
1974 rear bumper was 2 pieces, 1975-1982
used a one piece unit.

for 5 years.. 1970, 71, 72, 73, and 1974
Gymkhana Suspension was first introduced in
the 1974 Corvette.
1974 was the last year the Corvette would
be produced to run on "leaded" gasoline.
1975 first year for HEI distributor.
1975 was lowest production year for
convertibles for those years that offered both convertibles and coupes.
1976 Corvette used the same steering wheel
as a Chevrolet Vega for the "Sport Wheel" Option.
1977 last year for the notch back shark.
In 1977 crossed flags returned to the nose
and sides of the Corvette.
1977 saw the redesign of the center console
to accept standard Delco radios, the first year that Corvette didn't have
a Corvette only radio.
The '78 Pace Car was "Black and
Silver" was because it photographed well. Back then, most magazine
articles and ads were still done in Black & White!
The body in 1978 was widened in the rear
fender area. This was discovered by customizers when converting '78 and
newer coupes to convertibles after the convertible production ended in
1975.
1979 Corvette's highest production year.
By Federal mandate, the 1980 Corvette was
the first Corvette to have an 85 MPH speedometer.
1981 the first Corvette to use a computer.
The 1981 Corvette had two cooling fans to
increase engine power.
In 1981, Corvettes were produced with two
different types of paint. Lacquer was applied at the St. Louis plant, and
enamel was applied at the new Bowling Green plant.
In 1982 fuel injection reappeared in the
Corvette after a 17-year hiatus.
1984
to 1996
A total of 43 - 1983 model Corvettes were
built, but there were so many quality problems with them it was decided to
halt production until they could be corrected. By the time the problems
were corrected, it was so late into the model year that the car was
brought out as a 1984 model which was run for a year and a half. The
1983,s were never sold to the public and the only one that is known to
still exist is in the National Corvette Museum in Bowling Green, KY
The 1984 Corvette was the first American
production car to have a 64% windshield angle.
A single transverse plastic front and rear
spring first made it's appearance on the 1984 Corvette.
Twenty 1986 Corvettes were sent to Lotus in
England to be converted into LT5 powered prototypes for the ZR1 project.
In 1986, Corvette offered the "Malcolm
Konner Commemorative Edition" with two transmissions. A manual
4-speed and an automatic. Only 20 4-speed manual transmissions were
installed at the factory.
In 1987 you could buy a Corvette without an
engine installed by the factory.

production at the Bowling Green, KY plant
The LT4 exhaust system has a distinguishing
feature from the LT1 system. It has a balance tube incorporated into it!
96 Grand Sports: There is a small area
behind the hatch roof and in front of the panel that attaches to the rear
window that is taped, not painted. It is 1" long and the tape is
about 18" wide. This change was early in production. The purpose is
to eliminate a problem area in the paint booth during manufacturing.
96 Grand Sports: The Grand Sport's stripe
is not the same width all the way back. It gets wider as it goes up the
hood, and the top is narrower, and then it gets somewhat wider in the back
end.
1997
to ..
The first 200 production C5 Corvettes were
painted Red, not the traditional color for the first production run.
The 1997 Corvette C5 is the first Corvette
designed from the ground up to be a Corvette.. Not borrowing parts from
other cars. One of the few "Off the Shelf" parts - the exterior
door handles, same ones used on the Oldsmobile Aurora.
The first use of a transaxle in a
production Corvette occurred in the '97. However, the first plans for one
were in the Q-Corvette in 1958, planned for the 1960 model. Transaxles
showed up in Corvette prototypes in the mid '60s in running models.
The first 4 speed in a Corvette was built
by Borg Warner in 1957. The first transaxle in a production Corvette was
also built by Borg Warner, forty years later in 1997. Both were introduced
late in the model year.
Borg Warner has produced a transmission for
each generation of Corvette: C1 - 1957 to 1962, C2 - 1963, C3 - 1980 to
1981, C4 - 1984 to 1988, and C5 - 1997 to 1998.
