The Yenko dealership did not merely install performance parts, it also made modifications and provided race track ready tuning.

When the Camaro debuted, a General Motors corporate edict prevented it from carrying an engine larger than 400 in³ (6.6 L) V8.

Don Yenko and others knew there was a market for a more powerful Camaro and found ways around the GM limit.

Yenko also ordered the cars with COPO 9737 which included a 140 mph (230 km/h) speedometer, a larger 1 1/8th inch front anti-sway bar, and a special trim tag.

The cars had a Yenko Super Camaro serial-numbered tag in the driver's side door jamb and Stewart Warner pedestal-mounted tachometer and gauges were installed in the interior.

For 1969, the dealership worked with Chevrolet to have the L72 engines installed on the factory assembly line using a Central Office Production Order, or COPO.

The orders included power disc brakes, spoilers, cowl-induction hood, a 4.10 Positraction rear end with gears that were heat treated for strength, a bigger front sway bar, and a heavy-duty 4-row radiator.

As reported in the March '08 issue of Muscle Car Review, the vehicle is a fully licensed and certified Yenko starting at #202.
