I don't know what ya mean by w/o boring, I'd say the ones that are in there are as big as they need to be.

My buddy has his bored .040 over. The rumor I've heard is the reasonable limit is .050.

You can get a stroker crank, make it a 2.7L/2700cc.

i thought a balance and blueprint meant you stuff the largest sized pistons and smallest rings possible into a stock cyl wall without boring, and have the crank balanced? correct me if im wrong.

mudhippy... thats a nice option..... but damn, way too expensive for me.

O.K., will do.

Engine Blueprinting:

The basic concept of blueprinting is described as bringing the block into specification by re-machining the components of the block and sizing them to the original dimensions that the factory intended them to be.

Engine balance:

Engine balance is the design, construction and tuning of an engine to run smoothly. Engine balance reduces vibration and other stresses, and may improve the performance, efficiency, cost of ownership and reliability of the engine, as well as reducing the stress on other machinery and people near the engine.

Involves carefully weighing and shaping nearly every moving part in the engine.

Is this for a 22re or a 3.0?
If you need some machine shop recommendations from personal experience let me know as we are in the same area.

edit...what are the odds of 3 people on the same post in such close proximity?

That's basically the way I've always heard and used it. You are bringing the clearances and tolerances into factory spec. For example the factory says connecting rod clearance is 0.025mm to 0.055mm and so you size your rod bearings to match that. The actual diameter you machine the rod and crank aren't as important as the measurement of the clearance that your Plastigage says. The difference is that when the machine shop blueprints your engine, they have the crank, rods and bearings and do the work to match them all together rather than you telling them to turn the crank and rods to some fixed diameter that matches the bearings you bought.
