LS376/525

SKU: 19370413

Fuel-injected ferocity for performance cars of all ages

 

What do you get when you take Chevrolet Performance’s aggressive ASA camshaft — developed for the high-rpm world of circle-track racing — and slip it into an LS3 6.2L engine? The answer is 525 horsepower in one of our most powerful production-based crate engines. We call it the LS376/525, and if take-no-prisoner performance is what you’re looking for in your new Camaro or restomod Chevelle, this is it.

The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees of 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. And for durability, we complement the cam with higher-rate valve springs.

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 19259261), which includes the throttle pedal to match its electronically controlled throttle body. Check out our LS1 Engine Kit Installation Guide (P/N 88959384) for details on installing an LS engine in a vintage vehicle.
