Bill Jenkins won the first ever Pro Stock race in 1970 driving a 1968 Camaro with an Alu big block Chevy that was called a ZL1 but some say it was the 430 Cam Am block. They mention this car in the guest write up on Jenkins and it is listed with the other racing cars as a 1967 ZL1 Drag car but I do not know if this is the car that will be at the show.
