THE HOT CAM ADDS HEAT TO THE LS3Our 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 – 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-degree/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. 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.

FORGED INTERNALS SUPPORT MORE BOOST!For builders who want to stretch the performance of a turbocharged or supercharged combination, Chevrolet Performance’s LSX376-B15 is the foundation they need! Its durable, all-forged rotating assembly supports up to 15 pounds of boost. Our ratings of 473 hp and 444 lb.-ft. are only an indication fo what the engine is capable of. Additionally, the engine is topped off with high-flow, LSX-LS3 6-bolt rectangular-port heads to create an affordable foundation for supercharged and turbocharged combinations. We deliver the LSX376-B15 without an intake manifold and other accessories, allowing you to tailor the induction system and other features to suit the forced-induction setup of your choice. Our horsepower and torque ratings are based on testing with the production-style, normally aspirated fuel injection system. The power you make with a supercharger or turbo will vary.

AN LSX WITH BIG-BLOCK POWER!With the LSX Bowtie block, we’ve built a 21st century 454 with the latest technology. It’s lighter and more compact than an original Big-Block 454 – while delivering Big-Block output of 627 hp and 586 lb.-ft. – but requires no more space under the hood than a production LS engine. The LSX454 is filled with an all-forged, super-tough rotating assembly and features a pair of our deep-breathing LSX six-bolt cylinder heads. It also comes dressed with great-looking, orange powder-coated valve covers with engraved “LSX454” logos. Chevrolet Performance delivers the engine without an intake manifold and other accessories. Use LSX-LS7 singleplane carbureted intake manifold P/N 19244033. The LSX454 valve covers do not include provisions for mounting ignition coil brackets. Aftermarket or custom relocation brackets must be obtained. It also includes an 8-bolt crankshaft flange that may require an adapter for use with some transmissions.
