Seven Hills Motorcars is very proud to offer this beautiful 1970
L46 350ci 350hp Corvette
Coupe in excellent condition. The
car has been completely restored and is exceptionally clean. This Corvette
looks great, runs awesome, and is a spectacular driver that feels
great out on the road. It is finished in
the beautiful and highly desirable color combination of Mulsanne
Blue over Black Vinyl.
We have it priced to sell and are offering an excellent
opportunity to own a very desirable 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 C3 "chrome bumper" Corvettes
from 1968 to 1972 is absolutely red hot
right now and on the rise. The 1970 model year Corvette was only
made for 6 months and is the most rare of the "chrome bumper" years. There is no way someone could buy a
similar Corvette and restore it to this level of quality for
anything near our asking price. Please peruse all of the photos,
video, numbers, and other information below to get a true sense of
how nice this Corvette really is.
This 1970 Stingray rolled off the assembly
line during the first month of production in January of 1970.
The transmission is
correct and original with the last six digits of the VIN,
401504, stamped on the main case and pictured below as well
as the date code, P0S21A, which is November 21, 1969. The
previous owner stated that this is the original L46 350hp
engine in the car and he personally saw the last six digits
of the VIN and the suffix code stamped on the engine block.
As is common practice, when the engine was rebuilt during
the restoration the engine block was "decked" and as a
result of that process the original stampings were machined
off. There is some evidence on the car to support this claim
and that the car is an original L46. First, the car has a
6,000 rpm redline tachometer, which was only used on the
350hp L46 models. The L46 was only available with a 4-Speed
transmission, which this car has. The engine has a 3790010
casting number, which was used on 1970 L46 Corvettes. It
also has a "D 14 9" casting date, which with the GM strike
in 1969 would be possible for an early 1970 Corvette. We
removed the valve covers to see the cylinder head casting
numbers. Both cylinder heads have a 3927186 casting number,
which was used on L46 Corvettes. Both cylinder heads also
have a 1969 casting date that could be correct for an early
1970 model. Both exhaust manifolds also have correct casting
numbers for a 1970 L46 Corvette and the right manifold has a
3932465 casting number, which is particular to the 1970
model year. Since this car does not have a trim tag the
build month is easily determined by the production sequence
of the VIN. As once can see in list and breakdown of the
numbers below, this Corvette has many other correct and
original drivetrain components. The car also still has the
350hp data plate on the center console for an L46 model.
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.
1970 was the last year for high compression, truly full output, and
all out performance engines in Corvettes. The model years to follow
were more at the mercy of insurance companies, fuel prices, and
emission concerns. The 1970 Corvette saw the shortest production
time and lowest production numbers for any year of "chrome bumper"
Corvettes. Total production in 1970 was only 17,316, which was the
lowest since 1962. A strike at GM caused the 1969 model year to run
for an extra 4 months so production on the 1970 models did not start
until January of 1970. The body shape in 1970 was improved with
fender flares to reduce the damage from wheel thrown debris. Many
enthusiasts prefer the more pronounced fender flare and wheel
opening introduced this year. 1970 also introduced the iconic
"egg-crate" grills on the side of the car, which were only used on
Corvettes for 3 years and have become a symbol of the "chrome
bumper" Corvettes. The interior saw subtle improvements including a
redesigned seat for better headroom and better access to the storage
area. As in investment, the 1970 model year be particularly great
due to the rarity and the fact that this was the last year Corvettes
and muscle cars as a whole were purpose built for speed and
performance without the limitations from environmental and emission
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. All of the parts I checked follow this rule and
are dated correctly.
The first digit, "1," indicated the Chevrolet division of
GM. The "94" is the series, Stingray V8 Corvette. The "37"
is the body style, 2-door sport coupe. The sixth digit, "0,"
indicates the model year, 1970. The "S" is the plant where
the car was produced, St. Louis. The last five digits are a
sequence number so this is the 1,504th Corvette made for

1970 model year, which places the car's build date in
January of 1970.

Blue exterior is in beautiful condition. As one can
see in the photos, the finish has fantastic gloss, deep shine,
and smooth finish. Both doors open
and shut nicely. Please take a moment to look at all the
underside photos of the car. It is nearly as clean and well
detailed underneath as it is on top. The wheels and center caps
are in spectacular condition with no curb rash and a great finish.
The tires are virtually brand new and correctly sized 225/70R15.
The chrome and other bright work on the car looks great overall
with no rust or pitting. There is a small cloudy spot on the
front bumper and specific photos of the area below. The underside
of the car is very
clean and this Corvette has absolutely NO RUST ISSUES. The frame
is totally solid around the "key hole" area in front of the rear
tire and we have seen no evidence of corrosion around the
windshield or "birdcage." These are the most notorious spots for
rust on a C3 Corvette. We have included many photos of the
underside to show how great it looks.
This Corvette looks as good in person as it does in
Window Date Codes
Please note that almost
all of the glass on this Stingray, both of the the "Astro
Ventilation" door glass and even the pop out rear
window, is date
coded and original as each piece predates the car's body
build date of January 1970. Original glass is
a good indication that this car has had no major
and never sustained significant damage.
interior of the Corvette is in fantastic condition. The
seats look virtually brand new with no split seems, rips, or
signs of wear. The carpet is also new and in great condition
with no tears, holes, or stains. This includes the rear
carpet, which is often neglected. The dash is in
with no fading, cracks, or sun damage. The door panels are
in wonderful condition with no cracks. The radio in the car
is a Corvette specific unit made to fit this car so most
importantly the original dash was never cut or modified for
the installation. It also have an auxiliary source for your
phone to connect. This car has not been smoked in and
there is no aroma of cigarettes at all.
The interior looks as good in person as it does in
Corvette seems to be in good mechanical condition. It starts right away every time,
idles well, and runs great. According to the previous owner the
engine was rebuilt when the restoration was done. The bushings, tie rods ends, ball joints, and basically the
whole front end suspension is also new and was redone during the
restoration. The car is a awesome driver that feels nice 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 it drives smooth and the
car performs quite well overall. It runs cool and does not
overheat. There is no blue smoke when starting or driving the
car. The brakes are responsive. The shifter is tight, the
transmission does not pop out of gear, and the clutch feels
good. Also, the engine compartment is beautifully clean and
detailed as one can see in the photos. The engine also features
a very expensive Quick Fuel carburetor and a GM 3932472 Aluminum
Intake manifold. The intake alone sells for about $500 on eBay.
According to the previous owner the engine was rebuilt with an
LT1 spec camshaft and solid lifters.
The horn works as do all
the indicators, wipers, exterior lights, and interior lights. The entire vacuum
system for the headlights and wiper door works correctly from
both their respective switches on the dash and the override
switches. The entire operation from both switches can be viewed
in the video below. All of the gauges work with the obvious
exception of the clock and the speedo does not work. Some of the fiber optics work.
The blower is not working. Not
enough can be said as to how much of a pleasure it is to drive
this car, especially with T-Tops out on a beautiful day.
on the fiber optic light monitoring system. We
consistently receive many questions about the purpose of
this system; exactly what it is and what it does. The
sole and main idea behind the fiber optic light
monitoring system is to simply confirm that all of the
exterior lights, headlights, indicators, tail lights,
etc., are working and to make the driver aware of a a
burned out bulb. Each lamp on the outside of the car has
an actual fiber optic cable the runs to an indicator on
the center console. There are nine small indicators on
the console and each has its own finer optic cable. When
the bulb goes on the light travels through the fiber
optic cable and illuminates the corresponding indicator
on the console. If someone does not remember to plug the
cable end into the lamp housing, does any work to the
center console, or if there is a break in a connection
or anywhere along the cable, that indicator no longer
works. As one can image, over time this is very common.
Overall, this 1970 Corvette is in
very clean condition. The higher horsepower models like
the L46 always draw a great premium over the standard
base 350ci. In my opinion and based on our
experience the "Chrome Bumper" cars from 1968-1972 are
the most collectible and hottest in the entire Corvette
market right now and 1970 is particularly desirable due
to its rarity. The excellent condition, the
restoration, and the beautiful color combination make
this car especially important and difficult to
duplicate. This is an original a/c car, but there is no
compressor mounted as one can see in the photos. This Corvette always gets a ton of attention
driving down the road. It is very apparent that the
vehicle has been well taken care of by its previous
owners. The prices of C3 Corvettes have increased
drastically over the past 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.
