LS2 Engine Blueprint Illustration Series T-shirt

The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard powerplant for the 2005–2006 GTO. It produces 400 bhp (300 kW) at 6000 rpm and 400 lb⋅ft (542 N⋅m) at 4400 rpm 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 LS2 in the E-series HSVs are modified in Australia to produce 412 bhp (307 kW) and 412 lbft . The LS2 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 prod
