The Chevrolet Performance LS3 376ci/525HP 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 6.2L 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 with .525" lift on both sides, along with 226-deg duration on the intake side and 236-deg on the exhaust side. Coupled with a tight, 110-deg lobe separation angle, it 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.

Warning: This simple yet effective combination has an edge to it. You'll notice it in the idle quality and you'll feel it when the revs quickly climb. With 20 more horsepower than the larger-displacement LS7, it's definitely not for the timid!
