Yenko Nova 427
In the late ’60s, Yenko became known for a lineup of high-performance Camaros, Chevelles, and Novas, which featured 427 V8 engines unavailable from the factory. Also, all Yenko’s cars were dressed up with a unique stripe on the hood and on the sides and lettering “sYc,” which stood for “Yenko Super Cars .”
Amongst those fire-breathing machines, the Yenko Nova was the rarest and produced in just a handful of examples. It was introduced in 1970 and Don Yenko put the most powerful Chevrolet engine into the lightest body he could find. However, after initial testing, he stopped production after realizing that the Yenko Nova 427 was practically lethal (via Motor Trend).
