Original price was: $2,695.00.Current price is: $1,895.00.

Our LH6 5.3-liter Vortec Short Block Engine is on sale. This small block V8 is similar to the LY5, except the LH6 engine has an aluminum block. The easiest way to distinguish an LH6 from the rest of the 5.3 Vortec motors in the series is to verify that the vehicle’s 8th Vin digit is the letter “M.” This small block has been completely remanufactured at our state-of-the-art facility using upgraded parts to enhance the longevity of this engine. Taking chances with your basic remanufactured LH6 short block puts your vehicle at risk of an early failure.

OEM REPLACEMENT

Our LH6 short block engine remanufacturing process

Our LH6 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 that it precisely meets 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.
