LS376/480 HP 6.2L GMPP CrateEngine HotCam.
LS3 + Hot Cam = Loads of Fun
480 HP @ 5750 RPM, 475 lb-ft Torque @ 4500
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.
