Chevrolet Performance 427ci / 425hp COPO Crate Engine 2012-2015
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.
The COPO 427 for ''A'' Stock competition uses the large-bore cylinder block and high-flow cylinder heads of the LS7 engine and complements them with a high-compression rotating assembly to deliver big power from its large displacement. Its lightweight aluminum block and heads revive the spirit of the original ZL1 all-aluminum 427 big-block that helped forge the COPO legacy in 1969.2012-2015 COPO 427ci/425hp TECH SPECS:
