Seven Hills Motorcars is proud to offer this beautiful numbers
matching 1973 LS4 454ci big block Corvette
in spectacular condition.
This Stingray looks fantastic, runs great, and is an excellent
driver. The car is totally solid with nice lines and no
rust issues. The Blue-Green Metallic over Black color combination is
very rare and looks fantastic. It is also the correct and original color scheme
as verified by the codes on the trim tag, which is pictured below.
The previous owner recently spent over $9,000 on this car,
with receipts for all the work pictured below.
This is an excellent opportunity to own a classic original
big block Corvette that is
ready to be used and enjoyed at an unbeatable value. One could
easily buy this car now and sell it for more than the purchase price
in years to come as the market on C3 Corvettes is strong right now
and on the rise and 1973 is a special year. Please peruse all of the
photos, the extensive list of numbers, video, and information below
to get a true sense of how nice and clean this Corvette really is.
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.
If you have a question about the Corvette, just give us a
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 "Z" is the series, Corvette. The "67" is the body
style, convertible. 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 3,731st Corvette made for 1973.
Body Build Date
"C" corresponds to October, and "02" is the
of the month meaning this Corvette's body build date is
October 2, 1972.
"T" means the engine was build in the Tonawanda plant. The
"09" is the ninth month of year and the "13" is the
thirteenth day of the month meaning the engine was assembled on
September 13, 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 car.
Engine VIN Stamping
The last 6 digits of the car's VIN, 403731, 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
F 22 72
"F" is June, "22" is the twenty-second day of the month, and
the "72" is the calendar year so the engine
block was cast on June 22, 1972, which is correct as it
predates the assembly date.
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
I 8 72
"I" is September, "8" is the eighth day of the month, and
the "72" is the calendar year so the intake
manifold was cast on September 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 "207" is the
207th day starting with January 1, 1972, which indicates the
transmission is dated July 25, 1972.
Transmission VIN Stamping
The last 6 digits of the car's VIN, 403731, are stamped on
the main case meaning this transmission is original to this
AW W 192 E 1
The "AW" indicates a 3.08 gear ratio with positraction. The
"W" is the plant where it was produced, Warren, MI. The
"192" indicates the 192nd day of the year, "E" is the source
for the positraction, Eaton, and "1" is the shift in which
it was made. So this rear end was produced on July 10,
1972 in Warren, MI during the first shift.
"J" is May and "Y" is 1972 so this window was made in May of
"L" is March and "N" is 1971 so this window was made in
March of 1971.

and Mike Antonick's Corvette Black Book.
Metallic exterior is in nice 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 tires are correctly sized 225/70R15 and have
about 95% tread left. The convertible top is in excellent
condition with no holes or rips. The rear window is perfectly
clear with no fogging or yellowing. The top itself operates well
and goes up and down easily. There are a
few spots and blemishes in the paint and body around car with
specific photos below and some that
were too tiny to show up in pictures, but nothing else that is
really noticeable from about five or ten feet away. As one can
see in the many photos of the underside of the car, the bottom
of the car is
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
condition. The seats are in excellent shape with no
split seams or excessive wear. The driver's seat is not 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 door pulls are solid and intact. The
radio is a modern unit with Bluetooth and auxiliary inputs. Most importantly
it is a Corvettes specific unit made for this car so the dash has never cut or
modified. The jack and jack handle are still with the car
and stored correctly in the compartment behind the passenger
seat, pictured below showing the original decals on the
compartment lid. The spare is also still with the car. This
Corvette has never been smoked in; there are no burns marks
and no aroma of cigarettes.
The interior looks just as good in person as it does in the
This Corvette seems to be in good mechanical condition. As
stated above there are receipts totaling over $9,000 that go
with the car. The previous owner also said that he recently had
the engine rebuilt. The car
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 have recently been serviced and are responsive; they do not pull to one side or the other.
The transmission shifts well. This Corvette has a ton of power
with the 454ci engine. Also, the engine compartment is
beautifully clean and detailed.
The radio works as do all
the exterior lights, wipers, indicators, and all of the gauges
with the obvious exception of the clock. 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.
This is an original a/c car from the the factory, but the
compressor has been removed. The blower and the horn do not
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 and
the top down on a beautiful day
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 front end
treatment and 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 effort.
Thank you for looking and please do not
hesitate to email or call with any questions.
