I will be micrometerIng the cyl. walls and Piston grooves to see what their story is. The Block is not bad to the eye, I don't see lines in the vertical direction in the cylinder walls, we do have a ridge. The Rods feel good to the Pin. Rings get replaced and Bearings get replaced, that is a given. I do have the confidence to perform all but the Block magnaflux and Crank turning. I have the tools to do everything for a home build. I built the Trans. How hard can the Engine be. Part of me says do what I can and source out what I can't do. The other side is saying give it to the shop and get a short Block back, done. Let me measure this weekend and I will make my decision next week.

This is speculation at this point, speaking out loud:

The Honing I can do at home means I must use the type of rings that work with this type of stone. I read that I should take off no more than .010" and if the low areas disappear and the ridge is tolerable then a Ring job is all I need, that is if the Pistons past the test. The Rods and Pin look good to the eye, but they will be inspected with the Block and the Crank.

I would like to prepare the sharp edges off the block, hone the cyl to exactly .010, sand blast the Block inside and out, then bring that to the machine shop and have it magnafluxed as is. If he says it needs to be Bored, then that is that. I leave the Crank and Rods and Pistons with him and let him install the Cam bearings and decide the rest. If I need Pistons, then I will shop for the Pistons and Rings according to the size he wants. Then I can take it home and build it myself or if his price to finish the build is tolerable, then let him do it, especially if he guarantees the work. Even if he wants to clean the Block, after I do, that is OK, I'll take the guarantee. I will have removed every spec of Debrees in the Block, if I am allowed to use my sand blaster carefully, on the outside and inside of the Block. What are your thoughts?

P.S. I have a pressure cleaner for final wash down.
Every single thing you said right here, DO NOT DO IT. You do not have any idea what you are doing. Do not sand blast any part of that block. And DO not !!! try and hone your block and remove .002, let alone .010. You will ruin it as sure as the sun is going to come up tomorrow. When you hone a block at home, you remove nothing. No materiel to be removed.
So, leave all of this to a pro and do not do anything you are thinking in your head yourself.
Give this whole thing to a shop and let them give it back to you ready to install. This a a ever loving train wreck.
And, they are rod journals, NOT CRANK PINS !
If you think you need to hone out .010 by yourself, at home, THEN reuse the pistons you are telling everyone here you are a danger to that Pontiac block.
