The hot cam adds heat to the LS3 Our engineers never stop tinkering. When they took a production LS3 6.2L %28376 cubic inches%29 engine and swapped the stock camshaft for the racing-inspired LS Hot Cam%2C the result was a stunning 495 horsepower and 473 lb-ft of torque. We wasted no time in adding that terrific combination %96 dubbed LS376%2F480 %96 to our crate engine portfolio. The key to the power boost is the Hot Cam%92s 0.525-inch lift on both the intake and exhaust sides%2C along with 219-degree%2F228-degree duration specs. That%92s less lift on the intake side than the stock LS3 cam%2C but considerably more duration%2C allowing the valves to stay open a little longer to draw in more air from the rectangular-port L92-style heads. Use the LS376%2F480 with a controller kit%2C which includes a special pedal for use with the engine%92s electronically controlled throttle.
