Our LM7 short block engine remanufacturing process

Our LM7 short blocks have been remanufactured to perfection using our multifaceted process developed to not only match but exceed factory tolerances. Every block must pass our magnaflux inspection designed to detect any microscopic flaws or cracking. Blocks are then thermally cleaned, followed by steel microblasting until they achieve a brilliant appearance. Once a block is fully cleaned, we begin our precision boring and honing process. Using a carbon two-stage power hone, we can maximize the sealed area and ensure to precisely meet the recommended RMA readings. Computerized micrometers are used to resize rods in strict accordance with factory recommendations. Crankshafts are precision cut and micro-polished to achieve a 12 RMA reading or better. Before leaving our facility, every short block must clear our meticulous quality control evaluation that undoubtedly has the highest industry standards.
