1980 Chevrolet Corvette â?" Greenwood Daytona Widebody with 5.7 Liter H.O. 350 and Performance Upgrades Throughout Why This Car Is Special The 1980 Chevrolet Corvette was the last year of the C3 generation to offer the 350 cubic inch High Output V8 in all 50 states â?" a distinction that matters to buyers who understand what the emissions era cost the Corvette in raw performance terms. By 1980, Chevy had wrestled the L48 350 down to 190 horsepower in most configurations, but this particular car was built up well beyond that baseline. It carries the 5.7 Liter H.O. 350 designation you see on the air cleaner lid, supported by an MSD performance ignition system and chrome valve covers that confirm the engine has had attention paid to it.
