Curious!
I understand that the COPO, Yenko, ZL1 etc were given a 427 450hp motor. I have heard that on a dyno that these cars were getting around 560-570 rwhp. Were these engine numbers or rear wheel numbers? Did Chevy purposely down grade the motor that much {i think that would be insane to do}? Or was the 560-570 rwhp numbers just off a ZL1? [img]/ubbthreads/images/icons/confused.gif[/img]
Enlighten Me Please
