The Camaro was introduced in 1967 and brought with it the RS (characterized by hidden headlights), a muscular SS, and the high revving 302 cid Z/28. Chevrolet was at a disadvantage against its competitors across town inasmuch as GM prohibited Camaro engines larger than 400 CID. Enter Don Yenko, a Chevrolet dealer and performance enthusiast form Pennsylvania. Yenko began installed Corvette 427's into new Camaros and convinced Chevy personnel to approve a factory-built 427 for 1969, using a somewhat obscure ordering process typically reserved for fleets called the Central Office Production Order of COPO.
COPO 9561 featured a factory L72 427 boasting solid lifters and (a widely suspension understated) 425 horsepower with 4.10 gearing. COPO 9737, the Sport Car Conversion Kit, included 15-inch tires on Rally Wheels, a 140 mph speedometer, and a 13/16 inch front stabilizer bar. GM also offered COPO code 9560 for drag racing with an all-aluminum ZL1. That engine alone cost $4,000, nearly twice the cost of a base vehicle.
While Yenko Chevrolet is most closely associated with the COPO legend, other dealers quickly spotted the little-publicized ordering loophole. IN total, 1,015 street-legal Camaros were fitted with the L72 COPO option. This car came from Ewing Chevrolet of Canton, Ohio who - after Yenko - was one of the more prolific COPO dealers. It was ordered with both COPO 9561 and 9737 with racing in mind as attested to by early pictures of a tunnel ram hood scoop. Parked since 1978, it was lovingly restored in 2010.Also photographed at :
