Machining Processes:

  • Full CNC blue print machining, (bore, deck, hone and line honed)
  • The Cylinder bores are blue print bored to a true 90 degrees over the crankshaft center line
  • Diamond honed to within .0002 inch for precise piston to cylinder bore clearance.
  • Bored and line hone the crank bore housing to precisely align the crankshaft in the engine block.
  • Torque Plate Honed
  • The piston diameter measured to the nearest .0001 inch matched to cylinder bores.
  • The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface.
  • This is mandatory for proper sealing of a MLS Gasket.
  • Crankshaft - Balanced and Matched Rotational Assembly
  • Flexplate for Automatic transmission. (If you are using this for a manual transmission we highly suggest sending in your flywheel and pressure plate so we can achieve the best balancing job possible for your engine. Also, now is a great time to upgrade your clutch.)
