CHOATE 6.7L Short Block Workhorse Powerstroke Engine 6.7L Long Block Workhorse Powerstroke Engine 2011-2016 – Powerstroke Ford Diesel Engine Manufacturer: CHOATE Engineering Performance

CHOATE Part Number: CEP67PSW1116

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

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.

The main bore is align honed to precisely align the crankshaft in the engine block. The cylinders are bored 90 degrees over the crankshaft.

The piston diameter measured to the nearest .0001 inch matched to cylinder bores.

The block deck 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.

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.

Why you don’t want a Ford Reman Engine.

• ***Warning!***

  The Workhorse Platform is built for the working man. Made to haul heavy. This is a man’s engine. Made to tow big stuff. If you don’t have callouses on your hands, or have a man bun, do not buy this engine. The exhaust this engine generates will blow the skirt right off your effiminate body. If you are a lumber jack, or need something to haul your traveling act for grizzly bear wrestling, this engine is for you. Built by Men, Made for Chuck Norris.
