Edelbrock Victor 11-Degree CNC LS3 6-Bolt Cylinder Heads

Edelbrock Victor CNC 11-degree 6-bolt LS3 cylinder heads are specifically designed for high-horsepower, naturally aspirated, and boosted applications. Utilizing the popular LS 6-bolt design, they are compatible with the GM LSX block and all aftermarket iron or aluminum 6-bolt per cylinder LS race blocks. The design offers increased clamping capacity over the standard factory 4-bolt configuration and greatly improves head gasket sealing, making them ideal for high-compression naturally aspirated engines and high-boost applications. Edelbrock Victor CNC heads are manufactured with premium materials and machined to the industry's tightest tolerances. They have an 11-degree valve angle, copper infiltrated powder metal valve seats, and fully CNC-machined ports for maximum airflow. The machined runners and chambers, along with the valve angle increase overall flow capability, while the revised water jacket design enhances thermal conductivity and tunability. Premium manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricity, allowing the valves to seal securely, eliminating leak down and increasing cylinder pressure during engine operation. Finally, the .700 in. thick deck and reinforced rocker rails make these cylinder heads ideal for high-horsepower applications.

Chevrolet Performance LS3 6.2L 376 C.I.D 495 HP Engine Assemblies

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. 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.

Chevrolet Performance LS 376/525 LS3 Long Block Crate Engines

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.
