Our Factory Replacement Series LSx short blocks are a great solution for your worn out LS factory power plant. We start with an all-new Chevy LS short block and crank, add a set of Scat 4340 forged steel rods, and top it off with a set of Speed Pro Hypereutectic Pistons. We build each LS short block engine back to stock specs so you can use your factory or aftermarket performance cam and heads for a quick and easy install. Browse our LS short blocks for sale below and feel free to call our sales department to discuss your project today.
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 final assembly. Call our experts to upgrade your engine’s performance with a high quality LS short block today.
Aluminum LSx short block engines are compact, lightweight and can make lots of power. Every Competition LSx short block we build is assembled with top quality components from well known manufacturers such as GM, Callies, Mahle Motorsports, Wiseco, Clevite and ARP. We start with a brand new Chevy LS short block as a rock solid foundation for each build and then performance machine and prep each one in house. We balance and blueprint each engine to exact tolerances before we final assemble.
