Chevrolet Performance's COPO crate engines are engineered for NHRA's Stock Eliminator and Super Stock classes, offering sportman racers a range of factory-developed-and-assembled racing engines.

The 350, 396 and 427 naturally aspirated engines make a race car eligible for NHRA Stock Eliminator classes from AA/S to D/S, based primarily on weight and horsepower ratings. The 350 S/C engine makes cars eligible for AAA/S and AA/S classes. Consult the NHRA rule book at nhra.com for class and compliance guidelines.

Chevrolet Performance engineers designed and tested the engines with the same methods used to develop production engines, ensuring their performance and durability; and each engine is hand-assembled in a specially built facility.

COPO 327 2.9L S/C - 500 hp

Don’t let the smaller displacement fool you. This COPO racing engine packs a supercharged punch, thanks to a 2.9L Whipple twin-screw supercharger. It forces air into a pair of LSX-LS7 6-bolt heads mounted on a strong LSX Bowtie block, for a potent combination of exceptional power and strength.
