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.)
• Keyed Crankshaft
• Balanced and Weight 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. Get with our team to talk about the options we have available for you!)
