Clearancing block for 383

How difficult is it to clearance a block for a 383 stroker rebuild?

I've decided I'm at the very least doing a 355 rebuild, with new bearings, pistons, rods, and probably a crank. I figure, midaswell do a 383, but I'm not sure about clearancing the block myself.

It's not hard, but the block has to go to the machine shop anyway. I'd have them do it.

Watch your oil pan as well. I had a very small area that rubbed ever so slighty. A little tap from the ball peen hammer(It did not take much at all) and it rubbed no more. No leaks either.Like I said, hit it ever so slighty and continue to test fit it. Better to go small than way too much.

BTW: I can understand the DIY mentality. I have lots of things, once, to prove I could do it, learn something, etc. So if you want to DIY, I understand. In that case, a tip. Grinding cast iron require a good die grinder. The pneumatic types are far superior to the electric models - they are lighter, smaller, and more powerful.
