The 1957 Chevrolet Corvette Super Sport that General Motors proudly paraded around the show circuit nearly 65 years ago was no ordinary Corvette. It was, in fact, a game changer—the first to feature high-performance Ramjet fuel injection.

Developed by the team of John Dolza, E.A. Kehoe, Donald Stoltman, and Corvette chief engineer Zora Arkus-Duntov, and manufactured by GM’s Rochester carburetor division, Ramjet fuel injection offered increased power and accelerator response, faster cold starts, smoother engine warm-ups, the elimination of carburetor icing, and better overall fuel economy.The Rochester division tested two types of fuel injection methods: continuous flow, with the nozzle located directly outside each cylinder and spraying into the intake port; and timed, as in modern cars. The continuous-flow injection system was initially chosen due to its simplicity, and that’s what General Motors installed in the ’57 Corvette Super Sport that was unveiled at the New York Auto Show.

The 1964 Chevrolet Cheetah, designed and built by Bill Thomas Race Cars, was a limited production, Corvette-powered sports car intended as a direct competitor to the Ford Shelby Cobra, featuring a lightweight fiberglass body, a mid-mounted Chevrolet V8 engine, and a chrome-moly tubular chassis, all designed to deliver exceptional speed and handling, though hampered by production issues and a short lifespan due to Chevrolet's eventual withdrawal from the project; considered a rare and iconic American racecar with a cult following despite its limited production run and challenging racing history.
For the Cheetah, Thomas employed a front-mid engine layout, and a chrome-moly tubular chassis, with independent suspension borrowed from the Corvette. To achieve ideal weight distribution, he pushed the V8 so far back in the frame that the “driveshaft” consisted of little more than a flanged U-joint coupling.
