Re: GMMG ZL1
Did Chevrolet ever use the name ZL1 Camaro? I don't think so. The 1969 Corvette had an option called RPO ZL1 but the aluminum engine Camaro was option COPO 9560. There were prototype Camaros with ZL1 emblems but they did not escape the factory. Although it is well known today, I don't believe "ZL1 Camaro" was ever used as an official name in 1969.
