number matching 1970
L46 350ci 350hp Corvette

the car 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.
1970 was also the last year in Chevrolet before the emission
requirements started that limited horsepower. Please peruse all of the photos,
video, numbers, and other information below to get a true sense of
how nice this Corvette really is.
The low original mileage is verified not only by the
condition of the car, but also the clear Ohio title that is
pictured below showing the mileage as "Actual."
This Corvette is "Numbers Matching" meaning that the engine
that is in the car now is the same one that was installed in
the car new at the factory. There is a photo below of the
engine pad with a "403247" stamping showing the last six
digits of the car's VIN. The transmission is also original
with the last six digits of the VIN stamped on the main case
and pictured below.
The features of an original L46 are still present on this
Stingray. First, the car has a
6,000 rpm redline tachometer, which was used on the
350hp L46 models. The L46 was only available with a 4-Speed
transmission, which this car has and the transmission is
original. The engine has a 3790010
casting number, which was used on 1970 L46 Corvettes. Both cylinder heads have a 3927186 casting number,
which was used on L46 Corvettes. Both cylinder heads also
have a 1969 casting date that would be correct for an early
1970 model. As one 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 3,247th Corvette made for

"01" is the first month of year and the "29" is the
twenty-ninth day of the month meaning the engine was
assembled on January 29, 1970. This is correct as it
precedes the build date of the car.
This means the motor was intended for an L46 350ci 350hp
Corvette with a manual transmission, which is correct for

it predates the assemble date of the engine.
The intake manifold has the correct 3965577 casting number.
0 A 5
The "0" is the last digit of the calendar year. The "A" is
the first month of the year and the "5" is the fifth day of
the month so the alternator was made on January 5, 1970.

The left cylinder head has the correct 3927186 casting number.
Left Cylinder Head Casting Date

information obtained from Alan A. Colvin's Corvette by the Numbers
and Mike Antonick's Corvette Black Book.
Blue exterior is in good driver condition. As one can
see in the photos, the finish has fine gloss and deep shine. Both doors open
and shut nicely. The wheels and center caps
are in good condition with a great finish. Please note that it
has the correct and original 4 clip beauty rings, not the cheap
foreign made replacements.
The tires are correctly sized 225/70R15.
The chrome and other bright work on the car shows well overall.
There are a few small imperfections around the car that are
visible in the photos and some that are too tiny to show up in
pictures, but nothing else that is really noticeable from about
five or ten feet away. There is an spot behind the front bumper
that does not line up perfectly 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 February 10, 1970 (B10). Original glass is
a good indication that this car has had no major
and never sustained significant damage.
Black interior of the Corvette is in excellent condition and
appear to be completely original. The seats are in great
shape for original and look just in person as they do in the
photos with a very small amount of wear in the typical area
and the common dry foam. Please note that these appear to be
the original seats and vinyl skins, not some cheap
aftermarket covers or replacements. The carpet is also in
great original condition with no major stains. This includes
the rear carpet, which is often neglected. There are a few
spots worn through in the front foot well that are shown in
the photos below. The dash is in fantastic condition with no
cracks or sun damage. The door panels are in terrific shape
with no spits or cracks in the usual spot where the driver's
elbow sits. The door pulls are solid and intact. The
original radio works, but does not get good reception. Most
importantly the dash has never been cut or modified for an
aftermarket installation. The jack and jack handle are still
with car and stored correctly in the storage compartment
behind the passenger seat. There is a photo below showing
the jack and the original decals on the compartment door
lid. The original T-tops bags are also included with the car
and pictured below. 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 original interior is a
huge testament to the meticulous care this car has received
throughout its life and another great verification of the
low original mileage.
The interior looks as good in person as it does in
Corvette seems to be in good mechanical condition. The car is a awesome driver that feels nice the
road and at highway speeds. It starts right away every time,
idles well, and runs great. 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 and do not pull to one side or
the other. 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 horn works as do all
the indicators, wipers, exterior lights, and power windows. The entire vacuum
system for the headlights and wiper door works from both their
respective switches on the dash and the override
switches. The headlights come up fine, but take a long
time to come back down. All of the gauges work with the obvious
exception of the clock. Some of the fiber optics work.
The blower for the heater works on all speeds. Not
enough can be said as to how much of a pleasure it is to drive
this car, especially with the added power from the L46, the
4-Speed transmission, and the 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
excellent driver condition. Numbers matching is
extremely important in Corvette pricing and as one can
see, this car is quite correct. 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 very low
original mileage, and the great extent to which the
numbers match make
this car especially important and difficult to
duplicate. 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.
