Chevrolet LS3 376/480 480hp V8 Crate Engine

SKU: 19301358

Quick Overview

Chevrolet engineers never stop tinkering. When they 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 480 horsepower and 475 lb.-ft. of torque. That’s nearly 12 percent more power and torque from a simple camshaft change!

Chevrolet Performances ‘Hot Cam’ adds 50 hp to the already-potent LS3! Our engineers never stop tinkering. When they 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 480 horsepower and 475 lb.-ft. of torque. That’s nearly 12 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 a little longer to draw in more air from the rectangular-port L92-style heads.

Use the LS376/480 with controller kit P/N 19258267, which includes a special pedal for use with the engine’s electronically controlled throttle.

Purchase your Controller Kit at the same time as your Crate Engine and we will discount the Controller Kit to just £649.95!
