Description Technical Specs Extended Information
LS3 + Hot Cam = Loads of Fun!

The hot new small-block V-8 in the GM lineup is the hyper-aggressive LS3. It offers a high-revving 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-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" 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.
