6.7L Long Block Workhorse – Powerstroke Ford Diesel Engine Includes:

Before purchasing please verify the year model is compatible with your truck.
2011-2012 ;6.7 Powerstrokes Came 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.

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 (New Performance Stage 2)
  • 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. Call our Sales Team today for pricing.
  • New pistons, rings, Pin retainers weight matched prior to crank balancing (This is something even other competitors that advertise “balanced assembly” don’t do. All of our components are weight matched to 2 grams or less. This makes for an incredibly smooth and more responsive engine.)
• Head Machining
  • Pressure tested
  • New Valve Guides
  • Install new valve seals
  • Performance Valve Springs for better flow.
  • Surface cylinder heads to a 30Ra finish or better for proper MLS sealing
  • Cut and Install stainless O-Rings in Cylinder Heads to prevent head gasket failure

HX Bearings

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, consequently this increases reliability and allows for use of heavier weight oil.
• 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.
• OEM engines suffer from oil supply issues, however our 6.7’s see on average 5 lbs more oil pressure at startup than others due to machining processes.

Optional Parts are not installed. Optional parts are covered under the manufacturer’s warranty and not by CHOATE.
