Further Details on the 6.4L Powerstroke Engine:

Full CNC blue print machining, (bore, deck, hone and align honed).

We blue print bore the Cylinder bores to a true 90 degrees from the crankshaft center line, prior to diamond honing to within .0002 inch for precise piston to cylinder bore clearances.

We will main bore and line hone the crankshaft to precisely align the crankshaft in the engine block.

We bore the block back to the crankshaft center line and hone the block to Ra 13 finish. The piston diameter measured to the nearest .0001 inch matched to cylinder bores.

Cylinder block is surfaced to surface finish RA20 or finer, which exceeds the factory specification in both flatness and smoothness for the block to head sealing surface.

Common Issues With The Ford Powerstroke 6.4L (and how we fix them):

Piston Cracking- The 6.4L is plagued with cracking issues due to the design of the combustion bowl. We use a different piston that was originally designed for the commercial application of the engine to fix this problem.

Crankshaft Runout-Inherent crankshaft runout issues a recommend due to the low-speed-high-load design of the turbo systems (high boost at low RPM). This causes the crankshaft to runout of round, taking up the oil clearances for the mains and causing catastrophic failure.

We DO NOT approve the bending of the crankshaft to straighten, (which is common practice with many engine rebuilders) as material has memory and will result in a relapse of the original condition.

For this cause we machine the crankshaft to a truly round and concentric state from journal to journal. This allows the hydro-dynamic wedge created by the oil to do its job.

Our Dealers can use The policy below after the purchase of 3 motors:

If you have no core or the core is no good. (core must have no visible cracks or holes and rotate 360 degrees) core will be inspected and must meet Choate Engineering Performance specifications to deem it a good usable core.

The engine will be shipped to choate engineering performance in shrink wrap on a non returnable wooden & the appropriate core charge due. Failure to pay for core fees will void your warranty. Inspection of core takes approx. 30 days.

We require a like for like core. Meaning if we send you a long block we require everything from your core long block to be usable and machinable.

Any core engines not returned within the specified time will be subject to a restocking fee of 40 Percent

We will need the year, make, model, and vin number to make sure you are buying the correct engine before we ship.
