21. 1967 Chevrolet Corvette L-88
Chevrolet produced the second-generation Corvette (C2) from 1963 to 1967. It was one of the most beautiful and aggressive-looking cars of the muscle car era. In fact, the Corvette caused quite a sensation when it came out because it was modern-looking. However, Chevy replaced it with the third-generation Corvette in 1968. The Corvette C2 introduced many important things to the Corvette lineup. It offered big-block power, independent rear suspension, and disc brakes. It was also a popular and successful racing car in the hands of many private racing teams. Corvettes equipped with the L-88 engine were in a class by themselves since the aluminum head produced close to 600 HP.

Also, the L-88 had a mandatory heavy-duty suspension, brakes, and handling package. Chevy developed this option for racers. But it was expensive, almost doubling the price of the base ’67 Corvette. And that’s why it is one of the rarest, with only 20 in coupe and convertible form.
