Crate Engines

LS3 - 495HP Our engineers took a production LS3 6.2L (376 cubic inches) and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), which delivered a stunning 495 horsepower and 473 lb.-ft. of torque. That’s nearly 14 percent more power and torque from a simple camshaft change! We wasted no time in adding that terrific combination –

LS3 - 525HP 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.

dubbed LS376/480 – to our crate engine portfolio. The key to the power boost is the Hot Cam’s 0.525-inch lift on both the intake and exhaust sides, along with 219-de gree/228-degree duration specs. That’s less lift on the intake side than the stock LS3 cam, but considerably more duration, allowing the valves to stay open longer to draw in more air from the rectangular-port L92-style heads. The crate engine package includes the intake manifold, throttle body and fuel rail, along with the ignition system and exhaust manifolds. Use it with the LS376/480 controller kit P/N 19354330, which includes a special pedal for use with the engine’s electronically controlled throttle.

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.
