Total frame off restoration. All body parts redone on this rust free body prior to starting the process. The base coat, clear coat paint is Cortex silver with black stripes (copo) style. All new interior including headliner and has the original gauges. The rebuilt 427 big block runs great, with a rebuilt Muncie 4 speed shifter. It also comes with p/s and power brakes. The solid-lifter iron block and head L72 engine has a used aluminum manifold and a 800-cfm Holley four-barrel carb. Chevy rated it at 425 hp but the NHRA claimed a truer 450 hp. The block is stamped 3963512 which is a 1969-71, 427ci, 425hp period correct block. The 12-bolt positraction axle had 4.10:1 gears and is marked KQ0308 (March 8 1968) with a heavy-duty suspension. Front discs standard on Super Sport Chevelles, were a mandatory $64 option on COPO cars. From the SS version, GM borrowed the black grille and tail panel, hood bulges, side stripes, and chrome exhaust tips. However, there was no performance ID on the body. The interior was from a plain Malibu. To order one of these cars, all you needed were the COPO 9566AA or 9566BA codes and a dealer plus your check book. Original Yenko correct COPOs sell for $260,000 plus.
