Chevrolet Performance LS427 7.0L 570HP Crate Engine - Wet Sump

Not Available

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, high-lift camshaft helps it produce 570 horsepower and 540ft-lbs of torque. The new camshaft resulted in an increase of 65hp and 70ft-lbs over the production based LS7 crate engine. Additionally, a new wet-sump oiling system facilitates an easier installation without the hassle of adding a dry sump oil tank and running additional oil lines for the tank.
