Balancing & Blueprinting is nothing more than machining different engine parts to specific tolerances.

 

Balancing

 

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.

 

Blueprinting

 

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.
