I'm not sure if Trubble PMed you, but i'll just put this out for anyone who's interested.
All blueprinting an engine means that you check and adjust tolerances in the motor.
Example: Say a manufacturers specs call for a certain amount of forward/aft play in the crankshaft. Let's say .005 " (or 5 thousandths) Maybe your engine has .008 or more. That's a lot of play. Blueprinting an engine means that all of these specs are returned to factory, or tighter than factory if those specs are loose ( which a LOT of Ford specs are) This can be done through possibly adjusting torque settings, replacing bearings, or file fitting certain parts. Usually when you rebuild an engine, you will go by certain specs, such as torque specs, and clearance tolerances. This is basically blueprinting an engine. It just means you return the engine to it's original design specs ( or blueprints...get it). It's much more complex than that, but that's the basic premise.
