1969 Chevrolet Yenko Camaro 425 HP L72 V-8 engine


Description

Hi-Rise intake manifold

Daytona Yellow with Black vinyl top
Packed with a forged bottom end, forged aluminum 11.0:1 pistons, a high-lift, solid-lifter cam and a Holley 800 CFM 4-barrel on a high-rise aluminum intake, it was a seriously potent engine rated at 425 HP and it was central to the Yenko’s brutish character. However, the cost of these conversions was considerable, and selling the leftover L78 blocks was not an easy task, so in 1969, Yenko turned to Chevrolet Product Promotions Manager Vince Piggins, who shepherded Yenko’s request for factory-built 427-powered Camaros through the Central Office Production Order system. By 1969, Yenko had assembled a network of 36 dealers to sell his Super Car conversions, and it is believed that he was responsible for specifying the two COPO orders that constitute the full-bore Yenko Super Camaro package. First was COPO 9561, which, in addition to the L72 427/425 HP engine, specified a cowl-induction hood, curved-neck four-core radiator and F41 performance suspension. The COPO 9737 Sports Car Conversion Package added power front disc brakes, a 13/16-inch front sway bar, BE-code special heavy-duty 4.10 Positraction rear end, 15x7-inch wheels and a 140 MPH speedometer. Buyers also had a choice of a 400 Turbo 3-speed automatic or the Muncie M21 close-ratio 4-speed transmission in this exceptional example. The subject of a body-off restoration in 2004, the car is brightly finished in Daytona Yellow with a black vinyl roof and black standard interior.
