Engine & Transmission:
All engines were 350 cubic inches, with the base L-48 engine rated at 185 horsepower (except in California, which got 175 horsepower) and the upgrade L-84 engine rated at 220 horsepower.The engines in this era were burdened with emissions reduction equipment - this was the era of smog pumps with catalytic converters, which Chevy implemented by joining the exhaust into a single tube, passing through the catalyst, and then re-splitting the exhausts at the rear of the car. This bottleneck is somewhat responsible for the low horsepower numbers.
Transmission options included a 4-speed manual or 3-speed automatic.
1978 was the 25th anniversary year for the Corvette.
This was the first year of the "glass-back" styling with a large class window covering the trunk area.
1978 Corvettes are worth a bit more than their fin-back predecessors from 1975-1977.
6502 examples of the special edition 25th anniversary pace car model painted in black and silver-gray were produced in 1978.
