1967 Chevrolet Yenko Super Camaro.

One of only 54 made.

Debuting 26 September 1966, the 1967 Chevy Camaro was Chevrolet’s response to the wildly successful Ford Mustang. The Camaro differed from the Mustang with a more streamlined appearance, front partial frame for improved ride quality and to minimize and isolate noise. A rear unibody design helped save space and reduce production costs. However, it took several steps to change a regular Chevy Camaro into a Yenko Super Camaro.

For those who were in the know, they could opt to spec the Chevy Camaro with a Central Office Production Order, or COPO, package. Most COPO cars were special-purpose vehicles, such as ambulances, police cruisers, or taxi cabs that had to be built for the job they would fulfill. Cop cars and taxis take lots of abuse, while ambulances and the like must be constructed differently than regular passenger cars. For a Chevy Camaro fan, few things are as stirring as a COPO car that came with the L72 427 cubic-inch Mark IV Big Block mill. The L72 came with 11.0:1 compression, forged aluminum pistons connected to a forged steel crank, an radical solid-lifter cam, rectangular port heads, a high-rise intake manifold, and a big Holley 800CFM four-barrel carb, all combined to crank out 450 horsepower. The COPO order was necessary as GM had an internal rule that kept mid-size passenger car engine displacement under 400 cubic inches.
