4. 1967 COPO 427 Camaro (69 Made)
Chevy’s Central Office Production Order (COPO) program allowed customers to shoehorn the monstrous 427-cubic-inch big-block into a lightweight Camaro. The hand-assembled 427 V8—fitted with tri-power carburetors—cranked out approximately 425 horsepower and a gut-wrenching 460 lb-ft of torque.
Bolted to a four-speed M21 manual, the COPO Camaro blasted through the quarter mile in the low 12-second range at over 115 mph. Though the COPO process could have yielded several hundred units, Chevrolet deliberately capped production at 69 to preserve its racing legality, cementing the 427 COPO Camaro as one of the rarest and fastest muscle cars of its era.
