The Hot Cam adds heat to the LS3

LS long-blocks from Chevrolet Performance offer the core capabilities of complete crate engines at a low cost, allowing builders to finish the assembly their way. The LS376/480 long block is delivered without the intake manifold, coil packs, water pump, exhaust manifolds or other accessories

When our engineers took a production LS3 6.2L (376 cubic inches) engine and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), the result was a stunning 495 horsepower and 473 lb.-ft. of torque. That’s nearly 14 percent more power and torque from just a 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-in 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 a little 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 rails, along with the ignition system. Use it with the LS376/480 controller kit P/N 19354330.
