Seven Hills Motorcars is
Cincinnati's premier Corvette specialist anda licensed and
registered auto dealer by the State of Ohio. With many years of
focused experience we specialize in 1957 to 1982 Corvettes and other GM
classics. There is no other dealership that can better meet your needs
if you would like to buy, sell, or just find out more information about
your Corvette, Cadillac, Camaro, or Trans Am. Founded in 2005, this is
a very focused operation. We do it because we enjoy it. We are a
collectors and enthusiasts; therefore we look for cars that excite us.
I do not purchase at dealer auctions; each car is hand picked because it
is special or rare and because we like it.

Seven Hills Motorcars is
proud to offer this
1978 Corvette in great condition and with a 4-Speed manual
transmission and only 73,205 original miles. This Corvette looks
nice, runs great, and is an excellent driver; it is ready to be enjoyed. This is an excellent opportunity to own a
highly desirable classic Corvette
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 the C3 Corvettes
is strong right now and on the rise. The low original mileage is
verified not only by the condition of the car, but also the clear
Ohio title, pictured below, showing the mileage as "Actual." 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 call.
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
The first digit, "1," indicated the Chevrolet division of
GM. The "Z" is the series, Corvette. The "87" is the body
style, 2-door sport coupe. The fifth digit is the engine, L,
correct for an L48 car. The sixth digit, "8," indicates the
model year, 1978. The "S" is the plant where the car was
produced, St. Louis. The last five digits are a sequence
number so this is the 9,081st Corvette made for 1978.
Body Build Date
"C" corresponds to November, and "11" is the eleventh day of
the month meaning this Corvette's body build date is
November 11, 1977.
"V" means the engine was build in the Flint, MI plant.
The "10" is the tenth month of year and the
"28" is the
twenty-eighth day of the month meaning the engine was assembled on
October 28, 1977. This is correct as it precedes the build
date of the car.
This means the motor was intended for an L48 Corvette with
a manual transmission, which is correct for this car.
Engine VIN Stamping
The last 6 digits of the car's VIN,
409081, are stamped on
the engine pad meaning this engine is original to this car.
Engine Block Casting Number
The engine block has the correct 3970010 casting number,
which is correct for a 1978 Corvette.
Engine Block Casting Date
J 25 7
"J" is October, "25" is the
twenty-fifth day of the month, and the
"7" is the last digit of the calendar year so the engine
block was cast on October 25, 1977, which is correct as it
predates the assembly date.
Intake Manifold Casting Number
The intake manifold has the correct 14007376 casting number.
Intake Manifold Casting Date
J 25 7
"J" is October, "25" is the twenty-fifth day of the month,
and the "7" is the last digit of the calendar year so the
intake manifold was cast on October 25, 1977, which is
correct as it predates the assembly date.
The original carburetor has the correct stamping for a 1978
L48 Corvette with a manual transmission. The "170" means the
carb was produced after 1976. The fourth digit, "5," means
the carb was built in the 1976 - 1979 production run. The
fifth digit, "8," means it was built for the 1978 model
year. The six digit, "2," indicates that it is a 4BBL carb.
The seventh digit, "0," means is was built for the Chevrolet
division of GM. The last digit, "3," means it was intended
for use in a manual transmission car such as this.
Carburetor Date Code
The firth three digits, "264," indicate the
264th day of the
year. The last digit, "7," is the year in which the
carburetor was produced, 1977. So this carburetor was
stamped on September 24, 1977.
The "A" is
September and "G" is 1977 so the windshield is
original, made in September of 1977. This is correct as it
predates the build date of the car.
The "L" is August and "G" is 1977 so this window is
original, made in August of 1977. This is correct as it
predates the build date of the car.
The "Y" is
October and "G" is 1977 so this window is original,
made in October of 1977. This is correct as it predates the
build date of the car.
The "Y" is October and "G" is 1977 so this window is
original, made in October of 1977. This is correct as it
predates the build date of the car.

Metallic exterior is in good driver condition. As one can
see in the photos the finish has a great gloss and nice shine. Both door open and shut nicely as do the hood and headlights.
The YJ8 aluminum wheels and center caps are in
beautiful condition with a brilliant finish and no curb
rash. The BF Goodrich Radial TA tires are
virtually brand new and show almost no wear. There are
no major imperfections that have been intentionally excluded
from the photos. There are some touch-ups and other small
around the car that were too tiny to show up in the pictures,
but nothing that is really noticeably from about ten feet away. As one can see in the many photos of the underside of
the car, it is very 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
Window Date Codes
Please note that
ALL of the glass on this Corvette, even the windshield, is date coded and original as each
piece predates the car's body build date of November 11,
1977 (C11). Original glass is a good indication that
this car has had no major accident history and never
sustained significant damage.
The car looks just as good in person as it does
in the photos.
Black interior in this Corvette is in fantastic condition. The seats are in excellent condition
with no rips, split seams, or
signs of wear. They are not worn in the typical
area where the driver gets in and out. The carpet is
excellent condition with no holes, or stains. This
includes the rear carpet, which is often neglected. The door panels are in
wonderful shape with no splits or cracks and,
unlike many Corvettes of this age, they fit well and tight
to the door. The door pulls are solid and intact. The dash
and console look awesome overall with no sun fading, there
is a small blemish on the right corner of the dash pad. The
jack and jack handle are still with the car, stored
correctly behind the passenger seat, and pictured below
showing the original decals on the compartment lid. The original spare is
still with the car and still has the nubs on it. This Corvette features a modern radio
and sound system with hookups for an iPod or smartphone.
Most importantly, this radio is a Corvette specific unit made
for this car so the original dash was no cut or modified for
The interior looks just as good in person as it does in the
This Corvette seems to be in very good mechanical
condition. The previous owner of the car is a railroad mechanic
and said he spent about $3,000 in parts on the car. It starts
right away every time, runs well, and idle 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 clutch feels good, the car shifts nice, and
does no pop out of gear. This Corvette has plenty of power and
is quite fast. Also, the engine compartment is beautifully
clean, detailed, correct and complete as one can see in the
photos. Even the upper ignition shielding and original catalytic converter are still
radio works as do all the exterior lights, wipers,
horn, and all
of the gauges with the obvious exception of the clock. The blower works on
all speeds. The a/c
works and blows cold. The vacuum system for the
headlights works correctly. Also, the headlights
go up properly with either the headlight switch or vacuum
override switch. There 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 4-Speed and T-tops out on a beautiful day.
The car runs and
drives as well as it looks.
Overall, this 1978 Corvette is in
magnificent driver condition. Numbers matching is extremely
important in Corvette pricing, and as any buyer can see
this Corvette is extremely correct. This Corvette always gets a ton of attention
driving down the road. It is apparent that the vehicle
has been well taken care of by its previous owners. The
prices of C3 Corvettes have increased considerably over
the past several years. They are secure and wise
investments for a collector. 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.
