The new small block V8 in the GM lineup is the aggresive LS3. It offers a high revving 376-cid combination that represents generations of small block V8 development and engineering. Not only is the LS3 an amazing engine in its stock form, 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 50bhp!
The LS376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminium 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 to take the LS3 to the next level. this cam specs out with .525" intake and exhaust valve lift. Duration (@ .50") is 219 degrees intake and 228 degrees exhaust which allows for a dramatic increase in power. The engine will idle and cruise just like a LS3, but the power increase is there whenever you need it.
