The Corvette C1 sports car was produced from 1953 through 1962. In 1962, the GM Small-Block was enlarged to 327 and produced a maximum of 360 hp. One of the most important developments in the history of the Corvette was the development of the 265ci V8 engine that debuted in the 1955 Corvette. In 1956 the Corvette underwent its first major body transformation. This new exterior helped to establish the Corvette as a true performance car.
