Supercharged 355-Powered 1978 Chevrolet Corvette Silver Anniversary

Description

The 1978 Corvette's 25th anniversary was marked by the introduction of the special Silver Anniversary model, which featured a striking two-tone paint scheme of silver over gray with a separating pinstripe, a first since 1961. This commemorative edition, available with the B2Z option package for $399, also included aluminum wheels and dual sport outside mirrors, with mandatory additional options raising the total cost by another $380. Performance-wise, the model offered a choice between the base L48 engine, producing 185 horsepower, and the more powerful L82 engine, delivering 220 horsepower through a dual-snorkel air intake and an aluminum intake manifold. Reviews praised its impressive straight-line speed, with a 0-60 mph time of 7.8 seconds and a top speed of 123 mph. The Silver Anniversary model successfully celebrated the Corvette’s legacy with its distinctive design and enhanced performance.
