In '69, Chevrolet got their act together and put their 427 into such cars as this yellow '69 COPO Camaro.
Also in '69 came the pinnacle in GM muscle cars designed for the track, the ZL-1 Camaro. As discreet looking as this orange ZL-1 Camaro is, it could have very possibly surprised many street racers back in the day--until you popped the hood and saw the all aluminum 427!
Here is a red ZL-1 waiting for the street wars sure to take place later in the evening.
Picture this-take 427 cubic inches, over 450 horsepower, wrap yourself in fiberglass, sit 2 inches off the ground, and what do you have? This awesome '69 ZL-1 Corvette, of course! In the mood for some road racing?
