Chevrolet Preformance LS427
Chevrolet Performance’s new LS427/570 builds on the track-bred 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.
