I doubt any production ZL1 engine got near 575 hp. We worked with Bill Porterfield back in the '90s on a ZL1 dyno comparison. With a good tune up, open headers, no AIR pump, air cleaner or alternator it did 523 hp.

Camaro High Performance has rebuilt several. With racing oil and modern rings, they see 550+hp.
