Blueprinted??????
What exactly is blueprinting of an engine?????
I've always heard the term "balanced and blueprinted" but never understood the blueprinting part of it. Thanx Blygy |

My amature understanding of blueprinting is 'dry' assmebling the engine and measuring all the clearances and specs of the engine (crank play, bearing clearences etc) and making sure that all the parts are within specs before final assembly.

"Balancing & Blueprinting is nothing more than machining different engine parts to specific tolerances.
Balancing Balancing a v-8 engine requires 50% of reciprocating weight plus 100% of rotating weight, for a v-8 engine. Reciprocating weight: Piston, rings, wrist pin, and small end of connecting rod. Rotating weight: Big end of connecting rods, rod bolts & nuts, rod bearings, & oil supply to crankshaft bearings. Blueprinting Blueprinting an engine consists of several machine shop operations including but not limited to: Bore & hone cylinders (usually w/Deck plates). Re-size connecting rods (big end & sometimes small end). Turn & Index crankshaft. 3 angle valve job cylinder heads (to a specific width & place on valve face). Fitting valve guides to a specific clearance. Setting up valve springs to the right installed height & pressure, both open & closed. Surfacing block and cylinder heads straight & with the right RMS finish. Race engines require even more blueprinting----such as; cc'ing heads, machining for exact deck, block clearancing for crankshaft, & cam to rod clearance, porting & polishing, shot peening, heat treating,---the list goes on & on." -Ron's Precision Machining, Utah I guess what they are saying (http://www.rpmrons.com/Balance.html) is just what fargo said. Putting everything together, or atleast the things that need to be put together, and making sure everything fits into VERY tight guidelines. If it doesn't it is machined to. All engines should be balanced before assembly (don't let those crazy f0rd folks catch on to that one) but "blueprinting" usually denotes better build, more specific, more money so ultimately better engine. I don't know though. -Fox Deacon |

When a particular engine is designed, each and every piece has a specific dimension (length, width, height, and weight as well as material) When "blueprinting" everything is brought to original design specs, thus the term.

From what i understand, blueprinting is the little tricks your engine build does to your motor to increase hp.

That would be more like fine tuning it.
