Chevrolet Performance's COPO crate engines are engineered for NHRA's Stock Eliminator and Super Stock classes, offering sportsman racers a range of factory-developed-and-assembled racing engines. This COPO 350 Supercharged crate engine is the same engine offered exclusively in the COPO Camaro race cars.

Featured with a high-performance LSX engine block, forged internals that stand up to the cylinder pressures generated by forced induction, LSX cylinder heads with six-bolt clamping strength and a 2.9L Whipple screw-type supercharger. Chevrolet Performance engineers design and test all crate engines with the same methods used to develop production engines, ensuring their performance and durability. Each engine is hand-assembled in a specialty build facility.
