Both used solid lifters. Muncie four-speeds and Positraction 12-bolt rearends suspended from stock leaf springs completed the drivetrain.
The three Camaros he built were said to be Z/28s, though they may have started out as pedestrian Camaros with Z/28 markings. Smokey stressed that he deviated from stock by only adding rollbars, magnesium American Racing wheels, and 10.00-15 rayon racing tires.

Smokey flat towed one of the Camaros for this detour. When he got there somehow he was allowed to unload the Camaro at the track, where this shot was taken.
