Balancing & Blueprinting is nothing more than machining different engine parts to specific tolerances.
To balance 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.
To blueprint an engine consists of several machine shop operations including but not limited to:
Bore & hone cylinders (usually w/Deck plates) and hone to the correct clearance.
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.
