The 6.0 LS has been a staple of the GM community for boosted engines in all types of racing. We took the most reliable factory GM LS block and did our LME magic on it. We completely balance and blueprint this short block to handle the abuse that racers give it. Using Callies 8 CCW Crankshaft and Xtreme Rods, topped with Wisecos boost pistons this engine is good for 1500HP. Â
