About the LS427/570 Crate Engine

Chevrolet Performance developed the LS427/570 by combining a 427 cubic inch LS block with high-flow cylinder heads, a performance camshaft and a wet-sump oiling system suited to most chassis. The result is 570 horsepower with a wide torque curve that makes it as pleasant on the street as it is fast at the track. Because it is built from LS architecture, it works with familiar mounts, accessories and controllers.

Choosing an LS427/570 crate engine means you skip machining and assembly and start with a matched, engineered combination. It is a popular centerpiece for pro-touring Camaros, Chevelles, Novas and modern muscle builds.

Planning Your Install

• A Chevrolet Performance or aftermarket engine controller with the correct calibration.
• A fuel system capable of the power level.
• A transmission and rear axle rated for big torque.

Installation Tips

Follow the break-in instructions supplied with the engine, prime the oil system and verify fuel pressure before first start. Use quality synthetic oil once break-in is complete.
