• Head Studs included in our Daily Driver build, New Head Gaskets
• Full CNC blue print machining, (bore, deck, hone and line honed)
• The Cylinder bores are blue print bored to a true 90 degrees from the crankshaft center line, prior to being diamond honed to within .0002 inch for precise piston to cylinder bore clearances.
• We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block.
• We bore the block back to the crankshaft center line and hone the block to RA13 finish.
• 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.
• Connecting Rods, New Damper and Flexplate for Automatic transmission.
• All Manual will be charged the appropriate charges and will be balanced to a stock flywheel we have in stock or you will need to send in your Aftermarket in first.

Common Issues With The Ford Powerstroke 6.7L (and how we fix them)

• Main and Rod Bearing Clearance Issues- IE ,Spun Bearings. Our fix includes machining for the correct clearances as well as upgraded bearings designed to handle higher levels of stress.
• Valve Failures- OEM Exhaust Valves separate causing at the least, lost compression, at the worst, piston to valve contact causing catastrophic failure.
• We do not modify the existing valves as most do, we use an all new valve with better materials that do not have this high-heat separation issue.
• Crank Gear Spinning- Standard on all our 6.7L builds is a welded crank gear.
• From Ford this gear is prone to spinning, throwing off timing, and bending all 32 pushrods.
• TIG welding the gear in place eliminates this issue.
• Cam Tunnel Misalignment- The issue here comes with the aftermarket fix which is to use larger clearance bearings. This in turn causes low oil pressure.
• We do not use larger clearance bearings, we use our own proprietary bearings which allow for perfect alignment.
• Our 6.7’s see on average 5lbs more oil pressure at startup than others.
