- Chevrolet Performance LS3 LS376/525 6.2L 525HP Crate Engine
Fuel-Injected Ferocity for Performance Cars of All Ages
The Chevrolet Performance LS376/525 6.2L LS3 Engine is what do you get when you take Chevrolet's aggressive ASA camshaft, developed for the high-RPM world of circle track, and slip it into an LS3 crate engine. This 525 horsepower monster is one of their most powerful production-based crate engines, the new LS376/525! The ASA cam is a hydraulic roller that helps the engine deliver excellent throttle response and breathe exceptionally well at high RPM. For durability, they complement the cam with higher-rate valve springs to add stability to the valvetrain. This simple yet effective combination has an edge to it.
