Our Most Powerful Naturally Aspirated 6.2L!
With Chevrolet Performance’s 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 ? and one that has an edge to it. You’ll notice it in the idle quality and you’ll feel it when the revs quickly climb.
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 engine in a vintage car, you’ll need controller kit P/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.
This part replaces old P/N 19301360 & 19369338 & 19370413
Chevrolet Performance Crate Engines include a 24-month or 50,000-mile (80,000 kilometer) limited warranty.
