The Chevy 5.3-liter 325 LC9 Vortec Long Block Crate Engine Sale is here. The LC9 and LH6 are the only 325 engines out of the series that have a Flex-Fuel aluminum block. This 5.3L can be found in Chevy and GM trucks and SUVs from 2006 to 2009. Don’t get stuck with a rebuilt LC9 that can be prone to failure. Building a 325 long block takes some serious know-how. Our engines are completely remanufactured with upgraded components that have been specifically designed to extend the life of a 5.3-liter engine.

VIN Compatibility 8th digit: 3
This engine uses LM7 lifters so customers would need to delete the DOD (Displacement On Demand).

Description

OEM REPLACEMENT

Our precision remanufactured LC9 block

Every LC9 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.

Custom LC9 long block assembly

We meticulously mill each cylinder head until perfect alignment and sealing of the head gasket is achieved. Our cylinder heads are assembled using a new valve stem and seals that feature the latest high-temperature technologies increasing heat resistance and longevity. These polished cylinder heads are pressure tested using magnetic detection to eliminate the chance of cracks or flaws unseen by the human eye. Before each head is mated to their block using the correct torque valve, we vacuum test all seals for proper seating. Triple-angled cutters are used to machine the valve seats ensuring proper pressure and flow. All valves, valve springs, and valve guides must pass our stringent process of meeting and exceeding OEM specifications. O.H.C. heads are aligned for proper bore consistency. Every remanufactured long block has been specifically engineered to help improve the inherent flaws and failure points that can be found in many of today's engines.
