Product Overview
Brand new! 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 project, this is it!
The ASA camshaft is a hydraulic roller with .525-inch 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. 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 controller kit P/N 19259261, which includes the throttle pedal to match its electronically controlled throttle body.
Check out our LSX Swap Kits for options on installing an LS engine in a vintage vehicle.
