Chevrolet Performance LS3 6.2L 376 C.I.D 495 HP Engine Assemblies
The hot new small block V8 in the GM lineup is the hyper-aggressive LS3 6.2L 376 c.i.d. 495 hp engine assembly from Chevrolet Performance. It offers a high-revving 376 c.i.d. combination that represents generations of small block V8 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 boosts power by a whopping 50 hp!
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-revving, 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 in. intake and exhaust valve lift. Duration (at .050 in.) is 219 degrees intake and 228 degrees 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. A 14 in. automatic flexplate is included.
