Anyhow, the new COPO Camaro muscle car was clearly conceived with the same drag racing intentions as the nearly half a century old 69 COPO, in the Stock Eliminator and Super Stock NHRA (National Hot Rod Association) classes, and the new COPO is also available with the modern lightweight, and hand-built and naturally aspirated LS7 427 (7.0 L) small block, made famous by the Z06 Corvette, as one of the three power option choices.
The NHRA classes the COPO was designed to compete in generally run times in the nine second range, or better, on the quarter-mile today.
COPO specs: Also, the new Chevy COPO Camaro, or Camaro Stock Eliminator project, was in development before the new 2010 5th Generation Camaro even hit the highways. The new 3,175 to 3,250 lb COPO Camaro uses a production Camaro SS body (with the majority painted in white or black), has a standard solid Strange Engineering S-9 rear end unit with aluminum third member, 35-spline spool and 35-spline axles, 4.10:1 or 4.29:1 rear gearing, manual brakes and steering, full chrome-moly roll cage, lightweight semi-stripped interior, Hoosier racing tires (9.0/30.0R - 15 94.0 inch rear radial racing slicks with 4.5/28.0 - 15 inch fronts) with Bogart racing wheels (15 x 10 inch rear and 15 x 3.5 inch front), and a Hurst "Quarterstick" operated a 2-spd. automatic ATI "Pro Glide" automatic transmission and torque converter designed for the strip.

"Strange Engineering" played a significant role in the performance parts selection
COPO Camaro engines: These are the 3 high-performance engines to choose from. Published horsepower ratings for these COPO engines are, as is tradition, grossly underrated. The new COPO Camaro engines have a maximum recommended rpm of 7,500, and the NHRA horsepower rating is 550 hp for 4.0-liter supercharged 327, 500 hp for the 2.9-liter supercharged 327, and 425 hp for the LS7 427.
