A More Powerful, More Reliabilable GM LS7

The Chevrolet Performance LS427/570 Crate Engine is based on the race-winning production GM LS7 but is enhanced to bring a better, more powerful power plant. This engine features a new higher-lift camshaft to deliver 65 HP and 70 ft.-lbs. TQ increases over the production-based crate engine and a new F-car wet-sump oiling system to replace the remote oil-tank reservoir dry-sump system. Please note the aggressive nature of the camshaft calibration requires the use of LS427/570 Engine Controller and Harness Kit 809-19420000 (sold separately).
