Chevrolet Performance LS 376ci 495hp LS3 Long Block Crate Engines

If you take an already great LS3 engine and add a high performance racing-inspired Chevrolet Performance camshaft, the results are this completely streetable high performance engine with almost 500 hp and 473 lbs.-ft. of torque! The LS3 from the C6 Corvette and the brand new Chevy SS is already inspiring, but this modified version puts out over 50 hp more than in its factory form—and it provides a truly exciting heartbeat for your hot rod build.
