Starting with the '08 Corvette, the world was first introduced to GM's latest small block V8 creation – the 6.2-liter LS3.  Producing 430 horsepower and 424 lb.-ft. of torque. (In the Corvette, those numbers go to 436 hp and 428 lb.-ft. of torque with the optional dual mode exhaust system.)  This is now available as an aftermarket item with the LS3 Crate Engine.
The LS series of crate engines from GM have broken new ground for efficiency and performance from a pushrod platform engine. The LS3 engine continues the engineering breakthroughs with revised cylinder heads featuring rectangle ports borrowed from the LS7. The heads feature 63 cc combustion chambers, 2.16-inch intake valves, and 1.59-inch exhaust valves. The camshaft features an aggressive .551-inches of lift on the intake side with less overlap (than the LS2) for even greater airflow and power. Rocker arms with a 1.7:1 ratio sit on top of the heads.
In the bottom end, the aluminum 6-bolts/main block features 4.06-inch bores and 3.62-inch stroke. A nodular iron crankshaft, powdered metal rods, and aluminum pistons (10.7:1 compression ratio) round out a rev-happy short block. Red line for the LS3 comes at 6600 rpm, and you will get there very quickly.
With a high-tech GM foundation, aluminum block, and high flowing rectangular-port heads, the LS3 is the new standard in the small block world. The LS3 engine helps power the Corvette to a top speed of 190 mph, so what would an LS3 Crate Engine do for your project car!  You could also add one of the Edelbrock supercharger kits we stock to push the power of this engine up to either 554 or 599HP!

These engines are now supplied with the Chevy SS oil pan and exhaust manifolds rather than the Corvette items shown.
