In 1957, Don Yenko started selling aftermarket performance car parts at the dealership started by his father in Canonsburg, Pennsylvania. In the 60s, this was expanded to selling fully modified cars with the SYC (Yenko™ Super Car) name on the hood.

In 1969, Yenko ordered COPO Novas with factory installed 427 cubic inch engines. Yenko then added other modifications to make it a SYC. Kit features opening hood, 427 ci engine, separate door handles and wipers, detailed suspension and exhaust system, and more.
