Re: COPO ZL1 with the yenko performance pakage.
Brakes lines and air cleaner decals look the same to me. Also I think you said the car was a RS but the engine compartment you show is not a RS. They both even have the same incorrect master cylinder. Same welded on ports on the headers. If your friend insists that is a pic of his engine he is probably not that good of a friend.
