Our precision remanufactured L59 block
Every L59 Vortec 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.

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.
