Chevrolet Impala SS (1961-1969)

Chevrolet got in early on the muscle car scene with the 1961 Impala Super Sport, the first car to receive the SS high-performance package branding. In addition to a 348 CID or 409 CID V8 engine, the Impala SS got upgraded tires, suspension, and trim options. The 1969 Impala SS427, also known as the Z24, came with the 427 CID big block V8, and today is one of the most rare and coveted vehicles of the muscle car era.
