Nut and bolt rotisserie restoration completed five years ago COPO 9561 L72 427/425 HP V-8 engine MN-suffix block Winters aluminum intake 4-barrel carburetor Dual exhaust 4-speed transmission 12 bolt rear end with 4.10 Positraction Power brakes with front discs Special ducted hood Fathom Green with Green bucket seat interior Hurst shifter Norwood-built car with X44 code Painted XT steel wheels and hubcaps Goodyear Polyglas tires Camaro Hi-Performance Certified Certificate of Authenticity The term was referred to in racing circles as 7-liters, a 427 CI measurement that was to be the maximum for sanctioned competition engines. For Camaro buyers in 1969, that 427 CI possibility finally became a reality thanks to Chevrolet COPO process, which was a run-around for building special vehicles. COPO Camaros like the car offered here have since become among the most desirable releases in the first-generation series. Many of these special COPO 9561 vehicles spent their existence on the drag strip, and to bring one back to its as-built condition requires an intense understanding of its details and a willingness to locate the correct components. This car has the MN-suffix block that was the basis for the L72 427/425 HP V-8 engine. It is equipped with a Winters aluminum intake, 4-barrel carburetor, ZL2-design air-cleaner and dual exhaust. Date-code-correct components were used throughout, including the starter, bellhousing, fan blade, alternator and exhaust manifolds. The engine is backed by a heavy-duty Muncie 4-speed transmission and a 12-bolt rear end with 4.10 Positraction gear. This example has power brakes with front discs, the special ducted hood and is painted in Fathom Green with a matched green bucket-seat interior. Inside is the floor-mounted Hurst shifter, seat belts, in-dash tachometer and AM radio. Like many such cars, wheels were of minimal importance due to day-two replacements, and this car has the correct-but-narrow painted XT steel wheels and dog-dish hubcaps with F70-14 Goodyear Polyglas tires. Already Camaro Hi-Performance Certified, this spectacular COPO 9561 package showcases the 1969 Camaro body lines well, with the bulging hood and dual exhaust outlets telling the truth about its L72 powerplant.
