Our line of Street/Strip short blocks are a great start to your performance build. We start with brand new GM 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 the final assembly. Call our experts to upgrade your engine’s performance with high quality Ls short blocks today.

Our line of Competition LSx Short Blocks are built from top quality components from well known manufactures such as GM, Callies, Mahle Motorsports, Wiseco, Clevite and ARP.
