Please peruse all of the photos, the extensive list of numbers,
video, and information below to get a true sense of how nice and

This Corvette is verified as an original and correct big
block LS4 454ci model by the fifth digit of the VIN. This
car has an "Z" in the fifth digit indicating it is an LS4
while a base L48 has a "J" in that spot. The drivetrain on
this big block Stingray is numbers matching. The last six
digits of the VIN are stamped on the engine pad, which is
pictured below, and the engine is original to the car. The
transmission is also original with the last six digits of
the VIN stamped on the main case and pictured below.
As a side note, this Corvette is not a dealer auction
vehicle. We hand pick each car after careful
inspection. Our Corvettes come from owners who
expect their car to go to someone that will give the vehicle
the same care and attention as they did. We invite and
encourage you to examine the car in person or have the car
inspected. Please take the time to scrutinize each
picture. We photograph each vehicle to the greatest
extent so you can feel confident about your purchase.

The 1973 Corvette was truly the end of an era. 1973 was the last
year to feature a chrome bumper and is considered by some to be the
last year of truly classic Corvettes. Model years after were more at
the mercy of insurance companies, fuel prices, and emission
concerns, 1973 is considered the last "good" year by many
enthusiasts. The 1973 model year is also considered a special and
different year for Corvette enthusiasts as it was the only model to
have chrome in the back and a rubber bumper in the front. It is
representative of the transition Corvette was making at the time. As
in investment, the 1973 will always have an advantage and out
perform other years because of its precedence as the end of a a very
great period for Corvette and muscle cars as a whole.
Please note when checking the numbers that not only do the
correct stampings and casting numbers appear on the parts, but
all of the dates are also chronologically correct. This means
that all of the parts were made and assembled in the correct
order. For example, all of the dates for the individual engine
components and the engine casting date should obviously precede
the assembly date of the engine because the parts had to be
produced before they could be assembled. Most of the parts I
checked follow this rule and are dated correctly.
The first digit, "1," indicated the Chevrolet division of
GM. The second digit "Z" is the series, Corvette. The "37" is the body
style, sport coupe. The fifth digit is the engine, Z,
correct for an LS4 454ci Corvette. The sixth digit, "3,"
indicates the model year, 1973. The "S" is the plant where
the car was produced, St. Louis. The last five digits are a
sequence number so this is the 10,674th Corvette made for
Body Build Date
The body build sequence, "10674," places the car's build
date in very late December of 1972. This Stingray does not
have a trim tag so the build sequence can place the can
determine the month of production.
"T" means the engine was build in the Tonawanda plant. The
"11" is the eleventh month of year and the "27" is the
twenty-seventh day of the month meaning the engine was assembled
on November 27, 1972. This is correct as it precedes the
build date of the car.
This means the motor was intended for an LS4 454ci Corvette
with an automatic transmission, which is correct for this
Engine VIN Stamping
The last 6 digits of the car's VIN, 410674, are stamped on
the engine pad meaning this engine is original to this car.
Engine Block Casting Number
The engine block has a 3999289 casting number, which is
correct for a big block LS4 1973 Corvette.
Engine Block Casting Date
K 16 72
November, "16" is the sixteenth day of the month, and
the "72" is the calendar year so the engine block was cast
on November 16, 1972, which is correct as it predates the
Intake Manifold Casting Number
The intake manifold has the correct 353015 casting number
for a 1973 LS4 Corvette. This intake was only use on big
block Corvettes in 1973.
Intake Manifold Casting Date
K 10 72
November, "10" is the tenth day of the month, and
the "72" is the calendar year so the intake manifold was
cast on November 8, 1972, which is correct as it predates
the assembly date.
The "73" is the model year, 1973. The "C" means the
transmission was made for a Chevrolet vehicle, and the "S"
means is was intended for an LS4 454ci big block Corvette,
which is correct for this car.
Transmission Date Code
The assembly date code for the 1973 model year starts with
the first day of the calendar year in 1972 and continues
through the calendar year in 1973. This means "326" is the
326th day starting with January 1, 1972, which indicates the
transmission is dated November 21, 1972.
Transmission VIN Stamping
The last 6 digits of the car's VIN, 410674, are stamped on
the main case meaning this transmission is original to this
AW W 352 E 1
The "AW" indicates a 3.08 gear ratio with positraction. The
"W" is the plant where it was produced, Warren, MI. The
"352" indicates the 352nd day of the year, "E" is the source
for the positraction, Eaton, and "2" is the shift in which
it was made. So this rear end was produced on December 17, 1972
in Warren, MI during the second shift.

exterior is in excellent driver condition. As one can see in the
photos the finish has a terrific gloss, smooth finish, and deep
shine. Both doors open and shut nicely. The wheels are in great
condition with a brilliant finish and no curb rash on the beauty
rings. The BF Goodrich Radial TA tires have about
90% tread left. There are no major imperfections that have
been intentionally excluded from the photos. As one can see in the many photos of the
underside of the car, the bottom of the car is exceptionally
clean and this Corvette has absolutely NO RUST ISSUES. The frame
is totally solid with no rust around the "key hole" are in front
of the rear tire and I have seen no evidence of corrosion around
the windshield, which are the two most notorious spots for rust
on a C3 Corvette.
The car looks just as good in person as it does
in the photos.
The Black interior in this Corvette is in terrific
condition. The seats are in good shape with no split
seams looks just in person as they do in the photos. The driver's seat is not
overly worn in
the typical area where the driver gets in and out. The
carpet is also in fantastic condition with no stains or
holes. This includes the rear carpet, which is often
neglected. The gauge faces are crisp and clean and the
lenses are clear. The door panels are in good shape overall. The door pulls are solid and intact. The radio
works and most
importantly it is a Corvettes specific unit made for this
car so the dash has never cut or modified. This Corvette has never
been smoked in; there are no burns marks and no aroma of
cigarettes. Corvette interiors from this era are not known
to wear well, and the excellent condition of this interior
is a huge testament to the meticulous care and attention
this car has received throughout its life.
The interior looks just as good in person as it does in the
This Corvette seems to be in good mechanical condition. It
starts right away every time,
runs well, and idles smooth. It drives great and feels nice on
the road and at highway speeds. In the video below one can
observe the car accelerating on the highway up to about 70mph,
shifting through all the gears, braking to stoplight, and going
through some curves. Please note that there are no vibrations or
strange noises and the car performs quite well overall. The
brakes are responsive and do
not pull to one side or the other. The transmission shifts well
throughout the power band.
This Corvette has a ton of power and torque with the 454ci engine. Also,
the engine compartment is beautifully clean and detailed.
The horn works as do all the exterior lights, wipers,
indicators, radio, and all of the gauges with the obvious exception of
the clock. The blower for the heater works on all speeds. The vacuum system for the headlights works correctly
with no effort or binding in the mechanism. Also, the headlights
go up properly with either the headlight switch or vacuum
override switch. Their complete operation form both switches can
be viewed in the video below. Not enough can be said as to how much
of a pleasure it is to drive this car, especially with the power
from the big block.
The car runs and
drives as well as it looks.
Overall, this 1973 LS4 454ci
Corvette Stingray is in great driver condition. Big
blocks are very rare and draw a huge premium over a
standard Corvette. Numbers matching is very important in
Corvette pricing and as one can see this car is very
correct. It is a great value and we have it priced to
sell. The value of third generation Corvettes has
increased dramatically in recent times, this is
especially true for the 1973 model year. They are solid
and wise investments for a collector. 1973 was a very
special and one year only body style for Corvette that
is always recognizable with the newer and smoother front
end treatment with the classic chrome bumpers on the
back. While this is not an NCRS Top Flight or
Bloomington Gold car, it is a very nice driver quality
big block Corvette and a great car for the money. There
are photos below of the VIN stamp on the engine block,
suffix code, engine assembly date, transmission VIN
stamp, transmission date, and transmission codes. One
could easily enjoy this vehicle for several years and
sell it for more than the purchase price with minimal
