LS3 Crate Engine – Chevrolet Performance LS376/525 Long Block Engine

LS376/525 Long Block Crate Engine

Chevrolet Performance’s naturally aspirated 6.2 liter engine features an aggressive ASA camshaft developed for the high-rpm world of circle-track racing. Installed in the LS3 6.2L engine, it comes alive with 525 uncompromising horsepower. That makes it the most powerful naturally aspirated 6.2L street engine in our portfolio!

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.
