Chevrolet Performance has released its latest factory-engineered LS high-performance engine: the 376/525 LS3 long block. It blends the racing-derived ASA camshaft with the LS3 6.2L production engine to create the most powerful production-based crate engine in Chevrolet Performance's portfolio, delivering 525 hp at 6,200 rpm and 486 lbs.-ft. torque at 5,200 rpm. (For installation in older vehicles, the engine controller kit part number 19354332 is calibrated specifically for this new engine.) Using the LS3 production engine—the same used in Corvettes and Camaros—as the foundation for the LS 376/525 helped keep the retail price lower; while the ASA camshaft is a proven, power-building component that's been successful in the high-RPM world of Circle Track racing. The ASA camshaft is a hydraulic roller with .525-inch lift on both the intake and exhaust sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breath exceptionally well at high RPM. The cam also gives the LS 376/525 the most aggressive personality among Chevrolet Performance's growing lineup of production-based high-performance crate engines, which also includes the LS 376/480 and the carbureted LS 376/515. Front-end accessories must be obtained separately, along with the engine controller kit. Chevrolet Performance offers several accessory drive kits to suit a variety of applications; and some installations for older vehicles will require the oil pan changed. Engine specifications: * Power: 525 hp at 6,200 rpm, 486 lbs.-ft. of torque at 5,200 rpm * Displacement: 376 C.I.D., 6.2L * Bore x Stroke: 4.060 in. x 3.620 in. * Compression Ratio: 10.7:1 * Recommended Fuel: 92 Octane * Block: Cast Aluminum with 6-bolt cross bolted main caps * Crankshaft: Nodular Iron * Connecting Rods: Powdered Metal Steel * Pistons: Hypereutectic Aluminum * Camshaft: Steel Hydraulic Roller Tappet * Cam Lift: .525 in.

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. 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 in. intake and exhaust valve lift. 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.
