LS3 Crate Performance Engine
What do you get when you take Chevrolet Performance's aggressive ASA chamshaft - 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-prisoners performance is what you're looking for in your new Camaro or rest-mod Chevelle, this is it!
The ASA camshaft is a hydraulic roller with .525-inch lift on both the intake and exhaust 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 breath exceptionally well at high rpm. Chevrolet Performance complements this high-performance camshaft in the engine with higher-rate valve springs.
As delivered, the LS376/525 includes the intake manifold, with the injectors, fuel rail and throttle body already installed, along with the water pump and ignition system. Front-end accessories must be obtained separately, along with the engine controller kit. Chevrolet Performance offers several accessory drive kits to suit a variety of applications and some installations for older vehicles will require Chevrolet Performance’s Muscle Car Oil Pan Kit, part number 19212593.
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 LS1 Engine Kit Installation Guide P/N 88959384 for details on installing an LS engine in a vintage vehicle.
