The Corvette is a sports car that was produced by Chevrolet for the 1968 through 1982 model years. Engines and chassis components were mostly carried over from the previous generation, but the body and interior were new. It set new sales records with 53,807 produced for the 1979 model year.
1973 started Corvette's transformation from muscle to touring sports car. A Chevrolet advertisement headlined: "We gave it radials, a quieter ride, guard beams and a nose job." Indeed, redesigned body mounts and radial tires did improve Corvette's ride, and interior sound levels were reduced by 40%. Two 350 cu in small block engines were available. The base L-48 engine produced 190 hp. The L-82 was introduced as the optional high performance small-block engine (replacing the LT-1 engine) and delivered 250 hp. The new hydraulic lifter motor featured a forged steel crankshaft, running in a four-bolt main block, with special rods, impact extruded pistons, a higher lift camshaft, mated to special heads with larger valves running at a higher 9:1 compression, and included finned aluminum valve covers to help dissipate heat.
