Machining Processes

• 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 over the crankshaft center line
• Diamond honed to within .0002 inch for precise piston to cylinder bore clearance. (See Video)
• Bored and line hone the crank bore housing to precisely align the crankshaft in the engine block.
• Torque Plate Honed (See Video)
• 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.
• Keyed Crankshaft  (See Video)
• Balanced and Weight Matched Rotational Assembly  (See Video)

Flexplate for Automatic transmission. (If you are using this for a manual transmission we highly suggest sending in your flywheel and pressure plate so we can achieve the best balancing job possible for your engine. Also, now is a great time to upgrade your clutch. Get with our team to talk about the options we have available for you!)

  What you need to know about Choate Vs. the Competition. We have put together a list of videos for all processes we do to this engine. It is your responsibility to educate yourself about the differences. To do so we made that easier with this compilation of videos!

This is why we machine the crankshaft for an upgraded keyway!

What is Blueprint Boring?

This is why we square deck the block!

Why the WorkHorse Engine Comes with O-Ringed Heads

What’s the big deal about Choate Camshafts?

This is why we balance the rotational assembly!

Why do we encourage you to buy a long block instead of a short block?
