CHOATE Part Number: CEP67PSD1719

6.7L Short Block Daily Driver – Powerstroke Ford Diesel Engine Includes:

• Before purchasing please verify the year model engine is compatible with your truck.
• 2011-2012 6.7 Powerstrokes Come stock from Ford with a 8-bolt flexplate and torque converter that are no longer manufactured. All 6.7 Powerstroke balanced assemblies from Choate Engineering come with the updated 6-bolt flexplate from 2013+ and require the customer to update the torque converter or purchase one from us directly.
• 2017+ 6.7 Powerstrokes have a larger Hole Diameter for the motor mounts and bolts.
• Optional Parts are not installed. Optional parts are covered under the manufactures warranty and not by CHOATE.

This build includes:

• Full CNC blueprint 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 New Flex plate with automatic transmissions.
• Check both wrist pin and crank pin to rod clearances.
• New upgraded Pistons .10 – .30 inch over – New Pistons, Rings, Pin Retainers weight matched prior to crank balancing
• Crankshaft – Balanced with the Rotational assembly checked for run-out inspected for fatigue.
• Crankshaft is Polished and ground to .0005 concentricity or less
• New Rod, Main and Cam Bearings
• Camshaft – Polished and Inspected
• Install Rear Main Seal
• Install New Bed Seals
• Install New Rear Cover Gasket

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 large 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.
