Chevy LSx Short Blocks

Our line of Street/Strip LS engine short blocks are a great start to your performance build. We start with brand new GM LS short blocks and bring them through our machine shop where the cylinders are honed to ensure they are round and straight, crankshaft mainlines are line honed and oil clearances set on both main and connecting rod housings. From there we use new GM factory crankshafts, Scat 4340 forged steel connecting rods with ARP bolts, Mahle Motorsports forged pistons, Plasma Moly rings and Clevite Main and Rod Bearings. Rotating assemblies are balanced and all components are carefully inspected and cleaned before final assembly of these custom-built LS short blocks.
