- Chevrolet Performance 327ci / 500hp 2.9L Supercharged COPO Crate Engine 2012
Factory Engineered Drag Race Performance!
The power behind Chevrolet's winning COPO Camaro program is the factory-engineered racing engines tailored for NHRA's Stock and Super Stock classes. Those engines are now available from Chevrolet Performance for racers to use in homebuilt COPO Camaros and other race cars.
The COPO crate engines include a naturally aspirated 427 engine (7.0L) - the same displacement as the original COPO Camaros from 1969 - and two supercharged 327 (5.3L) engines - one using an LSX iron block with a 2.9L supercharger and the other using an LSX iron block and 4.0L supercharger. Both of the supercharged engines use Whipple twinscrew blowers.
The engines are built to specifications to make them eligible for competition in Stock and Super Stock. Chevrolet Performance engineers designed and tested the engines with the same methods used to develop our production and race engines, ensuring their performance and durability.

Don't let the smaller displacement fool you. Sized to fit the regulations of NHRA ''AA'' Stock, 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.
