Chevrolet Camaro ZL1 COPO
Back in the late ’60s, Chevrolet was under the General Motors racing ban. This meant that no official Chevrolet product could race, so Chevrolet couldn’t participate in any racing activity. However, nobody stopped Chevrolet from helping other racing teams through their “back door” programs, where they developed special engines and components. They installed 69 ZL-1s in those C.O.P.O Camaros, selling them to drag racing teams. The Camaro ZL-1 was the same on the outside as a regular 1969 Camaro. But it was so fast it was barely street-legal.
