Chevrolet Performance LS427/570 Crate Engine – Upgraded 570 HP Wet-Sump Edition

Chevrolet Performance LS427/570 Crate Engine

The LS427/570 is an upgraded LS7-based 7.0L V8 developed by Chevrolet Performance for high-performance and competition applications. It combines LS7 architecture with a higher-lift hydraulic roller camshaft and a wet-sump oiling system.

The engine produces 570 HP at 6,200 RPM and 540 lb-ft of torque at 4,800 RPM. The wet-sump design eliminates the separate oil tank and external oil lines required by the production-based dry-sump LS7 configuration.
