Chevrolet Performance LS427/570 Crate engine 

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.

 

Based on the Production LS7 Crate Engine

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. This engine comes assembled with the 14-inch Camaro Z/28 168-tooth manual transmission wheel. Use with LS427 Engine Controller P/N 19420000 (sold separately). Chevrolet Performance recommends 15W50 Mobil 1 engine oil for the LS427/570 engine.
