Every remanufactured engine is built to OEM or better standards, undergoing rigorous inspection and machining to meet or exceed original factory specifications. The process starts with 100% magnaflux crack detection on cast iron blocks, ensuring no hidden flaws compromise durability. Each block is precisely CNC machined and cylinders are honed to exact OEM cross-hatch patterns for optimal performance. Cylinder heads are resurfaced, inspected, and fitted with new valves, seals, and lifters-either OEM remanufactured or the highest-quality aftermarket options, selected based on which offers superior durability and reliability. Comprehensive pressure and vacuum testing guarantees leak-free operation. Only 100% new pistons, rings, bearings, seals, and critical components-never recycled-are used to deliver like-new performance and long-term dependability. Before shipment, every engine undergoes cold motored Sims testing to verify compression, oil pressure, torque-to-turn, and overall mechanical integrity. The result is a remanufactured engine engineered for maximum durability, reliability, and performance you can trust.

Product Features:

100% Magnaflux Inspection – Detects cracks invisible to the eye for superior reliability.
Cold Motored Sims Testing – Every engine is tested for compression, oil pressure, and proper operation before it ships.
