Chevrolet Performance’s new LS427/570 builds on the trackbred performance of the LS7 engine and enhances it in two important ways: More power and easier installation. A new, higher-lift camshaft helps it produce 570 horsepower and 540 lb.-ft. of torque—increases of 65 hp and 70 lb.-ft. over the production-based LS7 crate engine. Additionally, a new wet-sump oiling system facilitates easier and less costly installation, because the supporting components for the production-based LS7’s dry-sump system are not required.

Product highlights:

• Based on the production LS7 crate engine

• Unique high-lift hydraulic roller camshaft with.591-in. intake/ .590-in. exhaust lift
