Re: 428 questions
Sounds like you answered your own question... A 352 has a bore of 4.00. If you have a bore of 4.132 and a piston of .090, you need to make up .042 of empty space around the piston and the rings are going to work hard to fill a gap that big. I'm surprised you only lost one piston. Why didn't the engine builder use stock 428 pistons, another factor,...how much of the cylinder wall is left after cutting .132 thousands out of it, even if it was the HI-PO 352 there isn't going to be much left.
If that block is all you have take it to a local machine shop and let them check it out to make sure it's still OK and if so, hone the block just enough to clean it up and use 428 (4.130) pistons. Make sure you watch your temps. after you get it running.
If you can get another block, maybe a 390, (4.050 bore) and if the pistons (.090) are salvagable,... bore that block .040 thousands and you'll be in better shape.
