Description

**Optional Parts are not installed. Optional parts are covered under the manufactures warranty and not by CHOATE.**

This build Includes:

– Our Built-In-House Heads – Magnuflux and Pressure Test Heads, Grind 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 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.

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.
