6.2lt - 480hp


The LS series of engines from GM Powertrain have broken new ground for efficiency and performance from a pushrod platform engine. The LS3 continues the engineering breakthroughs with revised cylinder heads featuring rectangle ports borrowed from the vaunted 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 helps power the new Corvette to a top speed of 190 mph. What will it power you to?
