The hot new small block V8 in the GM lineup is the hyper-aggressive LS3 6.2L 376 c.i.d. 495 hp engine assembly from Chevrolet Performance. It offers a high-revving 376 c.i.d. combination that represents generations of small block V8 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 boosts power by a whopping 50 hp! 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.

Duration (at .050 in.) is 219 degrees intake and 228 degrees 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. A 14 in. automatic flexplate is included.

These powerhouses are the heart of the Corvette Z06 and feature 1.7L Eaton R1740 TVS superchargers spinning up to 20,000 rpm--enough to generate more than 9 lbs. of boost, along with big horsepower and torque. These LT4 long blocks have several unique features designed to support their higher output and the greater cylinder pressures created by forced induction. They include Rotocast A356 T-6 aluminum cylinder heads that are stronger and handle heat better than conventional castings, lightweight titanium intake valves, and stronger forged aluminum pistons.

Chevrolet Performance LS3 525 RLB 376/533 Racing Long Block Crate Engines
Chevrolet Performance's 525 RLB is based on the LS engine family and is like the 6.2L CT525 but sold as a sealed long block for universal racing sanctioning bodies. The high-revving 525 RLB crate engine is assembled with strong forged pistons and heavy-duty connecting rod bolts designed to support its performance capability and enhance its durability. With its deep-breathing LS3 rectangular-port cylinder heads, it is a combination rated at 533 horsepower at 6,600 rpm and a strong 477 lbs.-ft. of torque at 5,200 rpm, when used with a 4-barrel carburetor and intake manifold, per Chevrolet Performance testing. The engine assembly comes with coil-on-plug ignition and an SFI-certified balancer, along with a 6-quart racing oil pan and more.
