The hot new small-block V-8 in the GM lineup is the hyper-aggressive LS3. It offers a high-reving 376-cid combination that represents generations of small-block V-8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480—an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!The LS376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port L92 units that have been upgraded with high-reving, hollow-stem valves. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.The GM Performance Parts engineers picked the LS Hot Cam (P/N 88958733) to take the LS3 to the next level. This cam specs out with .525" intake and exhaust valve lift. Duration (@ .050") is 219° intake and 228° exhaust, which allows for a dramatic increase in power. The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it.14" automatic flex plate included.
