– ARP head studs included in our Daily Driver build, New Head Gaskets

– 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″ for precise piston to cylinder bore clearances. We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block. We bore the block back to the crankshaft center line and hone the block to RA13 finish. The piston diameter measured to the nearest .0001″ 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.

By buying you agree to have the engine core ready for pickup and return to us within 30 days of receiving the engine. Failure to do so will void your warranty.

Core will be inspected and must meet our specifications to deem it a good usable core. Mainline and crank must meet our specs as well. The engine will be shipped to Choate Engineering Performance in shrink wrap on a non returnable wooden pallet & the appropriate core charge due.

Once inspected appropriate core fees will be kept and balance remaining will be refunded promptly in the form of a check.

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.

We will need the year, make, model, and vin number to make sure you are buying the correct engine before we ship. We must know if the transmission is manual or automatic as this effects prices and usability. *if transmission is manual, we suggest purchasing a flywheel so we can balance it to a new flywheel. If customers flywheel is used the engine will be balanced to a stock flywheel.*

Front cover, oil cooler, oil pump are not included in our long block build. We install the following gaskets and parts new: bed seals, rear main seals, new rear cover gasket, upper and lower oil pan gaskets, pickup tube O-rings, rocker carrier gaskets, and rear cover. Valve covers are placed for shipping purposes only. The valve cover gasket is not included.

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. We do not use larger
clearance bearings, we use our own proprietary bearings which allow for perfect alignment.
Our 6.7’s see on average 5lbs more oil pressure at startup than others.
