When this car was new, I drove it as fast as it would go, just over redline in fourth
gear, or about 136 mph, west bound on I-80 west of Winnemucca, Nevada in
1971. It held the road like a Corvette should - the only thing scary
was the way I came up so quickly on the occasional much slower moving car.
One or two encounters like that was enough for me!
The handling and overall demeanor improved
significantly when I installed radial tires and Koni shock absorbers.
The only other "performance" modification I made in the early years was to
add a capacitive discharge ignition. Rather than improve
performance, the CD unit prevented the deterioration of the spark plugs
and points as the miles went by. It was like always having a fresh
tune-up.
In 1975, when the convertible Corvette was discontinued, I bought a
removable hardtop for this car from GM after having determined the
aftermarket tops did not have nearly the quality of the OEM top .
In 1986 I bought a new Corvette, and then
got heavily involved with CBX motorcycles.
The car was stored for 13 years
Thirteen years later, in the Spring of 2004, my CBX buddy Eric ragged on me to get the
car back on the road. He offered to come down from Oregon and help me
get it started in lieu of us attending a CBX rally in Carson City.
With my arm sufficiently twisted, I borrowed a pre-oiler, merely a
distributor with the drive gear, points and other ignition parts removed
removed. By plugging this tool into the engine in place of the
distributor and driving it with an electric drill, the oil pump pressurized
the oil system thereby lubricating the engine prior to starting. This
ensures adequate lubrication for an engine that has been sitting for an
extended time. We drained the gas tank too. Actually Eric, using the
time-honored method of sucking on the siphon hose, ingested some
good-tasting stale gasoline and got the flow going. With fresh gas and
a new battery the engine fired right up!
Thus began the process of bringing the car out of it's long sleep. New tires were
one of the first things replaced since despite having plenty of tread, the old ones had severely
flat-spotted from being parked so long. A lot of tinkering with
the carb, the brakes, and many small trim parts was done over the first
couple of years. In 2005 I had the front suspension rebuilt with new
bushings, ball joints, tie-rod ends, idler arm, sway-bar bushings and links,
and a new steering box. (Continued below photos)

Following the front end work, I had the rear suspension rebuilt with new
trailing arm bushings and wheel bearings, new parking brake hardware, new strut rods, and a single leaf
composite rear spring. After a four-wheel alignment, it rides and
handles like it did when it was new. Better in fact, since modern
radial tires are so much better than those bias-ply F70/15 white stripe
tires the car came from St. Louis with. The bias ply tires would trammel, or follow ruts or uneven
pavement, much more than even the widest low profile radial tires, and
certainly much more than the "modest" 60 series radials on the car
now. The bias ply tires were also very hard to get balanced so the
car wouldn't shake at some speed.
Once the running gear was brought back I replaced the original 30+ year
old exhaust with a chambered 2.5 inch system that was killer loud and fun to drive - the
chambers were like those on the RPO side pipe exhaust. I can't believe
those sounded as loud as this system does - I think having the headers in
front of this system made it a lot louder than it would have been with the
factory exhaust manifolds. Maturity finally caught up with me and I
had a couple of Magnaflow stainless steel mufflers put in the stock location
in the rear fenders. It sounds much better, not stock quiet, but
mellow with a snarl when I get on the loud pedal.
The exhaust was followed by a electronic ignition system buried in the old
points style distributor. With the points eliminated, I had Dave
Westgate re-curve the mechanical and vacuum advances in the distributor -
this made a HUGE improvement in performance, it now runs as a well built small block
Chevy V8 should! Throttle response is excellent, it has plenty of
low rpm torque, and it has great mid-range and top end power.
Stainless steel brake hoses and a new reproduction master cylinder (the
old one functioned perfectly, but it looked terrible - that's a good
excuse to replace a part, right?) took
care of the brakes in 2008. I also replaced the original clock that no
longer worked with a quartz unit and restored the center gage cluster "while
I was at it". Oh yeah, the other "while I was at it" involved
correcting an annoying oil leak from the engine. I heard about
FelPro's one piece oil pan gasket, since the car was up on stands what
better time to replace the pan gaskets. I'm now a true believer in
this new technology.
Next I replaced the corroded chrome exhaust bezels, which can
hardly be seen unless you crane your neck under the back of the car.
I was going to replace the coolant hose clamps with OEM style Witek until
I learned the clamps on the car are original, so I won't be replacing
them.

History |

The reference to Shark
above is because this generation of Corvette has become known as
shark because their appearance, including the nose, grill, and
gills in the sides of the fenders. This 3rd generation is
now commonly referred to as C3, a numbering scheme that didn't
start until at least the forth generation which ran from 1984
through 1996, and included my 1986
model.
In the beginning, of course, they were just Corvettes. Then in
1963 we got the Sting Ray (notice it is two words). After
the Sting Ray we got Stingray, the C3s. At that time the
Sting Rays were known as MidYear Corvettes, and still are
often called that, although nowadays C2 is preferred by most
people. The C1, or Solid-Axles ran from 1953
through 1962, or 10 model years. C2 production run was pretty short with
only 5 model years. They are probably the most
obtainable and valuable
of collector Corvettes - the C1s are often worth more, but there
are not as many of them,
So we come back to the C3 generation, the longest running in
Corvette history, 1968 through the 1982 an amazing 15 model years!
During this time the Corvette changed a lot in many ways.
Body-wise, we have the Chrome Bumper series, '68-'73, although the
'73 only had chrome at the rear. Starting in '73 and through
the end is the Rubber Bumper series, and this is further broken
down by cessation of the convertible after 1975, and replacing the
flat rear window and flying buttress "sails" with a fast-back
bubble rear window in 1978.
One reason for the long C3 production run was this was the period
Detroit had to clean up engine exhaust to meet smog regulations.
It was also the beginning of the safety requirements, the rubber
bumpers being the first visual manifestation. So we saw
horsepower reach a zenith in 1968-1969 and then slowly drop off as
unleaded fuel and other EPA requirements took hold. Big Block
engines of 427 and 454 cubic inches disappeared after the 1974
model year. What the later C3s lacked in raw power they made
up in refinement and comfort options. The cars got slower
but quieter, smoother riding, and more comfortable.
Naturally, with this long production run there were a lot of C3
Corvettes built: 542,861 to be exact, more than any other
generation to date.
My C3 or Shark, being the second model year is more of a rough and
tumble car than the later ones, but it is an accurate reflection
of how they were built back then.

| Theme |

Old cars are usually maintained or brought back with a
particular theme in mind. Today in the 21st Century, we have
so many choices facing us it is almost bewildering to
contemplate. Electronic fuel injection, five and six speed
transmissions, air conditioning add-on kits, power rack & pinion
power steering, hydraulic assisted power brakes, modern suspension
components from newer Corvette generations, the list is
practically endless. I thought a lot about which direction I
should take this Corvette. In the end, I decided that except
for the engine, I would keep the car as near stock as I could, and
keep it as original as possible. I don't intend to have it
judged by the NCRS , but from now on, every part that goes into or
on the car will be as close to NCRS standard as possible.
The major distractions to that concept are the entire engine,
exhaust system, and the stainless steel braided brake lines.
BUT, the saving grace, so to say, is that the ORIGINAL, numbers
matching engine is perfectly good, and after a sympathetic
overhaul, it can go back in the car, along with the original
carburetor and all the smog equipment - all things that are
important for an NCRS judged Corvette. The exhaust and brake
lines can easily be replaced with OEM parts, so a future owner
could conceivably frecive favorable treatment by an NCRS judge if he or she desired.
With all this in mind, I have directed my energies toward making this
Corvette a period-correct, early 1970s, moderately hot rodded Corvette - that's my theme and I'm sticking to it. |
