A bigger, more powerful next generation small-block!

With the all-new LS2, GM has once again raised the bar for production-based small-block V-8 performance. The 6.0-liter LS2 builds on the success of the popular LS1 V-8 engine with more displacement, power and technical innovation. Our LS2 is built right here at CBM and comes with forged rods and pistons to make this LS2 even more Durable and dependable.

The LS2 is built on a new cylinder block, which shares much of its design with the previous LS1 V-8 design, including a deep-skirt, six-bolt-main block with structural oil pan. Subtle differences include the crankcase vent moved to the top of the valley, relocated knock sensors and the cam sensor moved to the front of the engine. The LS2's cylinder heads are high-flow pieces used previously on Corvette LS6 engines.

The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard power plant for the 2005-2006 GTO. It produces 400 bhp (300 kW)@6000rpm and 400 lb·ft (542 N·m)@4400rpm from a slightly larger displacement of 5,967 cc (5.967 L; 364.1 cu in). It is similar to the high-performance LS6, but with improved torque throughout the rpm range. The LS2 uses the "243" casting heads used on the LS6 (although without the sodium filled valves), a smaller camshaft, and an additional 18 cubic inches. The compression of the LS2 was also raised to 10.9:1 compared to the LS1s 10.25:1 and the LS6s 10.5:1. The LS2s in the E-series HSVs are modified in Australia to produce 412 bhp (307 kW) and 412 lb·ft (559 N·m). The LS2s in the Chevrolet Trailblazer SS and the Saab 9-7X Aero are rated at 395 bhp (295 kW) (2006-2007) or 390 bhp (290 kW) (2008-2009) and 400 lb·ft (542 N·m) of torque due to a different (sometimes referred to as a "truck") intake manifold that produces more torque at lower RPMs.

The LS2 is also used as the basis of the NASCAR Specification Engine that is used as an optional engine in NASCAR's Camping World Series East and West divisions starting in 2006, and starting in 2010 may also be used on tracks shorter than two kilometers (1.25 miles) in the Camping World Truck Series.
