Long Block

– Our built in house Heads
Magnuflux and Pressure Test Heads, Cut Valves, New Induction Hardened Seats, All New Valve Guides, Install New Valve Seals, Test Spring Tension, New Freeze Plugs, New Injector Cups

– Head Studs included in our Daily Driver build, New Head Gaskets

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

The Cylinder bores are blue print bored a true 90deg from the crankshaft center line, prior to being diamond honed to within .0002″ for precise piston to cylinder bore clearances. Main bore ( line bore) for the crank shaft is linked bored to precisely align the crankshaft in the engine block. Bore block back to crankshaft center line Hone Block to RA13 finish. Piston diameter measured to the nearest .0001″ 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.

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%.

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

CHOATE Engineering Performance Crate Engine Features :

• 600 HP rate.

•  Designed with the working man in mind. The perfect platform for those who do heavy hauling regularly. Fully balanced.

• Upgrades over the Daily Driver include but are not limited to: O-Ringed Heads; Billet Flex Plate; Coated, Fly Cut and Delipped Pistons; Stage 2 Cam; Chromoly Pushrods; Welded Cam Gear;

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

Piston Cracking- The 6.4L was 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.
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.
