Machining Processes

• Block Machining
  • Full CNC blue print machining, (bore, deck, hone and line honed).
  • We blue print bore the cylinder bores to a true 90 degrees from the crankshaft center line.
  • Diamond hone within .0002 inch for precise piston to cylinder bore clearances.
  • We  line hone the crankshaft bore housing to precisely align the crankshaft in the engine block.
  • We bore the block back to the crankshaft center line.
  • The piston diameter measured to the nearest .0001 inch matched to cylinder bores.
• Balanced Rotational Assembly
  • Crankshaft – Balanced with the Rotational assembly checked for run-out inspected for fatigue. Crankshaft is Polished and ground to .0005 concentricity or less
  • Camshaft- Polished and Inspected
  • Connecting Rods
  • New Damper
  • New Flexplate for Automatic transmission.  This would be a great time to replace your clutch as well. If manual your crankshaft will be balanced to a stock pressure plate, and flywheel. Now would be the the time to upgrade to a performance clutch. It would allow all these components to be balanced together for the best result.
  • New upgraded Pistons .10- .30 inch over – New pistons, rings, Pin retainers weight matched prior to crank balancing
• Head Machining
  • Magnuflux and pressure tested
  • Installed press seats
  • New Valve Guides
  • Install new valve seals
  • Performance Valve Springs for better flow.
