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 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-degrees duration on the intake side and 236-degrees on the exhaust side. Coupled with a tight, 110-degree 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.

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!

You'll need tuning to make the most of the engine in a late-model GM vehicle. If you plan to use the LS376/525 in a vintage car, you'll need the controller kit (p/n 809-19259261), which includes the throttle pedal to match its electronically controlled throttle body.
