the sheet that came with my pistons reads:
min. max
3.000-3.624 .0020 .0060
3.625-3.999 .0025 .0065
4.000-4.199 .0030 .0070
4.200-4.500 .0035 .0075

my question is ...that seems like a lot of differece in clearance and which one should I use... says go towards the min for light mods and towards the max for heavy mods....I just want to know whats better. sorry I am a noob in this area...

Something doesn't look right. You bought it from Woody didn't you? If so, call him.

All of the pistons I've ever bought had one number, not a range. Usually .004-.007 depending on the brand.

they are probe industries forged srs pistons....and the machine shop is balancing my crank but what exactly does that involve I am curious for my own knowledge. wish I had the know how and the equipment to do this stuff on my own I love learning and doing new stuff like this

They should be balancing the entire rotating assembly, not just the crank.

well thats what I mean I guess but what does that involve?

[woody1]

The 4.030 probe piston will measure 4.028 at .500 from the bottom of the skirt, finish hone the cylinders to 4.032-4.033. As for balancing they need everything I sent you so they can weight the rods, pistons etc, then spin the crank and take weight from it. It will end up with a few holes in the front and back counterweights.

Blueprinting is just writing down all the specs and tolerances on a sheet of paper.

thats kinda what I thought but wasnt sure I hear older people say it alot and this guys pretty old but anyways yeah he has done some chevys but he says his preference is working on ford small blocks so we will see
