#15 – 1967 Chevrolet Corvette L88
The 1967 Sting Ray was the last Corvette of the second generation, and refinements done throughout five years made it the best of the line. The ultimate Corvette motor for the 1967 was coded L88, which was even wilder than the L89, and was as close to a pure racing motor as Chevrolet had ever offered in regular production. Although the L88’s factory rating was advertised having 430 bhp at 4600 rpm, but the engine’s true rating was said to be about 560 bhp at 6,400 rpm. Only 20 of these were produced.
