The Yenko Super Camaro was a modified Chevrolet Camaro prepared by Yenko Chevrolet, developed by the dealership owner and racer, Don Yenko. Background When the Camaro debuted, a General Motors corporate edict prevented it from carrying an engine larger than 400 in³ (6.6 L) V8. This put the Camaro at a disadvantage to the Ford Mustang, Plymouth Barracuda and the Dodge Dart since neither Ford nor Plymouth/Dodge had such a limit (although Ford only had a 390 Mustang in 1967). Don Yenko and others knew there was a market for a more powerful Camaro and found ways around the GM limit. 1967 Yenko ordered L78 equipped SS Camaros and swapped in the Chevrolet Corvette's L72 427 in³ (7.0 L) V8. The cars came with a 4.10 rear end and heavy-duty suspension. The approximate number of cars produced is 54. Yenko also installed a fiberglass replacement hood similar to the "Stinger" hood featured on 1967 big-block Corvettes. The Camaros were equipped with a M21 transmission. The horsepower was rated at . 1968 Encouraged by the success of the 1967 model, Yenko continued to produce his Yenko Super Camaros for 1968. The 1968 Yenko Super Camaros started life as Super Sports with L78 396 in³ hp engine and close ratio 4-speed Muncie transmission. Yenko also ordered the cars with COPO 9737 which included a speedometer, a larger 1 1/8th inch front anti-sway bar, and a special trim tag. Yenko swapped out the factory 396 in³ short-block for the L72 427 in³ short-block reusing the rest of the 396 in³ engine's components including the heads, carburetor, intake manifold, etc. He swapped the stock hood for a twin-snorkel fiberglass hood and added Pontiac's 14"x6" steel wheels with special Yenko caps, Yenko emblems gracing the front grill, front fenders and tail panel. 427 emblems were added to the tail panel and front fenders as well. 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. Early cars got a rear spoiler made for Yenko and later cars all got the factory spoilers front and rear. The recognized production number for these cars is approx 64 cars converted, with well less than half of that number known to exist today. 1969 For 1969, the dealership worked with Chevrolet to have the L72 engines installed on the factory assembly line
