Product Description

Features of New TK Long Blocks

  • New GM OEM Oil Pan
  • Harmonic Balancer
  • Front and Rear Engine Covers with Seals
  • Top Engine Valley Cover

The LS6 designation was also used on a 454 CID Chevrolet Big-Block engine of the 1970s, as well as an iteration of the GM Iron Duke engine from the late 1970s

The LS6 is a higher-output version of GM's LS1 engine and retains the same capacity. The initial 2001 LS6 produced 385 bhp (287 kW) and 385 lbf·ft (522 N·m), but the engine was modified for 2002 through 2004 to produce 405 bhp (302 kW) and 400 lbf·ft (540 N·m) of torque. The LS6 was originally only used in the high-performance C5 Corvette Z06 model, with the Cadillac CTS V-Series getting the 400 bhp (300 kW) engine later. The V-Series used the LS6 for two years before being replaced by the LS2 in 2006. For 2006, the Z06 replaced the LS6 with the new LS7. The LS6 shares its basic block architecture with the GM LS1 engine, but other changes were made to the design such as windows cast into the block between cylinders, improved main web strength and bay to bay breathing, an intake manifold and MAF-sensor with higher flow, a camshaft with higher lift and more duration, a higher compression ratio of 10.5:1, sodium filled valves, and a revised oiling system better suited to high lateral acceleration. LS6 intake manifolds were also used on all 2001+ LS1/6 engines. The casting number, located on the top rear edge of the block, is 12561168. Applications:
