Our precision remanufactured 351 Windsor block

Every 351 block must pass our magnaflux inspection designed detect any microscopic flaws or cracking. Blocks are then thermal cleaned followed by steel micro blasting 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 with strict accordance to factory recommendations. Crankshaft's are precision cut and micro polished to achieve a 12 RMA reading or better.

Custom 351W 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 in 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 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 pressures 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.
