What the third generation is, and what you will find here.
The third generation Corvette ran from 1968 to 1982, fifteen model years, longer than any
other Corvette body style. It arrived as a road-going take on the Mako Shark II show car, with
pop-up headlights, removable roof panels and a removable rear window, and it left as a fuel
injected Collector Edition with a glass hatch. In between it absorbed just about everything the
1970s could throw at a sports car: emissions rules, impact bumper standards, an oil crisis and
a fuel economy panic. What is remarkable is that it stayed a two seat sports car through all
of it.
That long run is also why C3s can be confusing to identify. A 1968 and a 1982 share a
silhouette and almost nothing else. Chrome bumpers gave way to body-colour urethane, the big
block came and went, the removable rear window disappeared and returned as a fastback, and the
last cars were built in a different state by a different plant. Two cars that look alike from
across a car park can be years and a great deal of money apart.
Working out what you have
Most people arrive here holding a number they want explained. The
VIN decoder reads the chassis number and tells you the year, body style
and assembly plant. The RPO decoder translates the option codes on the
trim tag into the equipment the car actually left the factory with. The
build date decoder goes one step further and works out when your
car was built, to the day for St. Louis cars and to the week for Bowling Green cars. Behind
those there are reference tables for engine codes,
casting numbers, paint colours,
options and production figures.
Keeping one on the road
The mechanical side of a C3 is friendly. The small block Chevrolet V8 is the best supported
engine in the hobby and very little on the drivetrain is hard to find. The traps are structural
rather than mechanical, and they are worth knowing before you buy: these cars rot in the
birdcage and in the frame rails, both hidden behind bodywork that can look perfectly sound. The
FAQ covers the questions owners ask most, and the how-to pages here run
from a five speed conversion and a ZZ4 engine swap
through to rebuilding the dash clock.
Cars from readers
Alongside the reference material, readers have been sending in their own cars for years.
There are now over 150 of them in the owners showcase, sorted by the
year they were built, each with the owner's own account of what they have and what they have
done to it. Together they are a decent picture of how these cars are actually owned: survivors
next to rebuilds, show winners next to driveway projects. If you have one,
send it in.
