CHOATE 6.7L Long Block Daily Driver Engine 6.7L Long Block Daily Driver Engine – Powerstroke Ford Diesel Engine. Manufacturer: CHOATE Engineering Performance
CHOATE Part Number:CEP67PLD1719
Here is something you probably didn’t know. Many remanufacturers reuse parts that you thought you were getting new, like pistons and lifters. Not to mention all the corners cut in the machining processes. We take the time to show you what we do, so you can understand and appreciate what a great engine build takes. We aren’t the cheapest, and you can’t afford for us to be. We wouldn’t want to compromise the quality you deserve.Â
6.7L Long Block Daily Driver – Powerstroke Ford Diesel Engine Includes:
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.

Pressure Test Heads
New Upgraded Valves (See Video)
All New Valve Guides,
New Valve Seals
New Freeze Plugs.
Head Studs
Full CNC blue print machining, (bore, deck, hone and line honed) (See Video)
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 cylinders are bored 90 degrees over the crankshaft.
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.

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.
Our 6.7’s see on average 5lbs more oil pressure at startup than others.
 “Is balancing really important? Diesel engines turn slower than gas engines, so therefore it isn’t as important…….”
Balancing is extremely important for anything that rotates. It’s just as important to balance a diesel as it is gas engines, watch this link to better understand why. The Daily Driver lasts longer because it is not only balanced but also has a matched assembly.
What is blueprint boring? And do I actually need it?
“Why will you guys not cut price and just grind the valves?”
Why do we use the HX Bearings?
Watch this video to see all of the problems of the 6.7 PSD Engine and how we fix them.
DCR Conversion Option the Fix for the Fuel System Failures!
No more expensive CP4 pump failures to worry about with your 6.7L Powerstroke. Choate Engineering uses this opportunity to save you 10-15K dollars if your pump was to fail. By changing out the old fail prone Cp4 for the much more durable DCR.
