Chevrolet Camaro ZL-1
The Camaro ZL-1 was the same as the regular 1969 Camaro on the outside. But it was so fast that it was barely street-legal. The official 1969 Chevrolet literature doesn’t mention the ZL-1 option for the Camaro. But if you were a successful drag racer or a dealer, you knew about this expensive option. That is why only 69 Camaros ZL-1 left the factory (via Supercars).

The secret of the Camaro ZL-1 was its engine. It was high revving, 7.0-liter V8 with around 550 HP in mild tune. Chevrolet produced about 200 of those engines, and while most of them went to Can-Am racing teams, 69 of ZL-1 were installed in C.O.P.O Camaros and sold to drag racing teams.
