Discontinued - LS2 6.0L without ECM and Wire Harness - 2006 Model Year, has 58X reluctor wheel

A bigger, more powerful next-generation small-block from the new Corvette! With the all-new, 400-horsepower LS2, GM has once again raised the bar for production-based small-block V-8 performance. As the standard engine in the 2005-’06 Corvette—as well as the ’05-’06 Chevy SSR and ’05-’06 Pontiac GTO—the 6.0-liter LS2 builds on the success of the popular LS1 V-8 engine with more displacement, power and technical innovation.

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. High-tech features, such as an electronically controlled throttle, make the LS2 a state-of-the-art performer.

The LS2 crate engine comes complete with a composite water intake manifold, electronically controlled 90 mm throttle body, fuel rail with injectors, balancer, exhaust manifolds, water pump and a 14” flexplate for automatic transmissions. PN 19156261 comes with a Corvette oil pan installed and PN 19159564 comes with a GTO-style oil pan installed. The LS2 can be adapted to older cars and street rods. A handy reference guide (see page 70) is available to help install the engine in older cars with minimal guesswork.
