LSx Short Blocks

Street/Strip Short blocks

Our range of Street/Strip LS engine short blocks provides an excellent foundation for enhancing your performance build. We kickstart the process with brand-new GM blocks, meticulously refining them in our state-of-the-art machine shop. Here's how we do it:

  1. Precision Cylinder Honing: We start by honing the cylinders to ensure they are perfectly round and straight, setting the stage for optimal performance.

  2. Crankshaft Mainline Precision: Our expert technicians perform precise line honing on the crankshaft mainlines, ensuring top-notch engine durability and efficiency.

  3. Fine-Tuned Oil Clearances: We carefully set the oil clearances for both main and connecting rod housings, guaranteeing smooth and reliable engine operation.

  4. High-Quality Components: New or fully inspected blocks, GM factory crankshafts, Scat 4340 forged steel connecting rods equipped with ARP bolts, hypereutectic pistons, Plasma Moly rings, and Clevite Main and Rod Bearings. These premium components are chosen for their performance and durability.

  5. Balanced Rotating Assemblies: To ensure perfect harmony within your engine, we meticulously balance the rotating assemblies, reducing vibrations and enhancing longevity.

  6. Thorough Inspection and Cleaning: Before final assembly, all components undergo thorough inspection and cleaning, ensuring that your short block meets our rigorous quality standards.
