I am listening to you and I appreciate your involvement.

Since these Pistons are most likely going to be replaced, I am using them to teach myself where and how to measure them.

The Block needs extra cast flashing and the sharp edges bumped/removed, so that this procedure will prevent cracks in the future, where using a 3" round soft metal wheel in a drill, using slow speed to remove the paint. I can't depend on some shops to go out of their way in order to perform over and beyond their call of duty to remove casting flaws, we did the same on my Th 400, so we are good at it, trust us. I elected to service the Block and we have pulled the freeze plugs, only. On the exterior of the block, we removed most of the paint. We will clean the Block tomorrow with Dawn soap and a soft brush, in order that we may obtain our own set of gauge readings and precise measurements, ones that I can record in my own book, as I have been doing for the last ten years.

For example, look what happened when I brought the Heads to the shop and the machinist said that he would cut the exhaust seat bosses back to the proper size, then changed his mind and just installed a better seal over them.

When this Block goes to the shop, I will ask him to Magnaflux it and depending and depending of the outcome and if the Block is usable, we will let the shop go to work on it. I would have the Cam Bearings removed, inspect the Cam and Crank alignment in the Block, shave the Deck, and whatever they recommend.

I will bring the Pistons in on their Rods, along with the Cam and Crank to be inspected.

Once I get that report/information from them, then I will post the prognosis and we can talk about it from there.

Thank you all for your help, just to recap, this is either going to be a light build or if it needs to be Bored over, I just as well make it into a stroker SD clone. I will let the same shop build it as long as I get a warrantee for one to three years, if they will. It will come home as a short Block in a Bag. I have no doubt that I can build a motor, just not this one. It is one (1967 428 ci "special equipment" HO YK code) of 1035 ever made.
