I know you are replacing the engine, which is an easy way to solve your VERY big problem, but I must answer your question here, because someone else answered wrong.
Using one oversized piston with all others of "normal" size is not a problem. In fact, the factory used to do that quite often in the old days before the machining equipment could make very consistent bore diameters and piston sizes.
It was NOT uncommon at all to find engines straight from the factory with oversized bores on one or two cylinders. They would mark it with special punch marks on a certain spot on the block (described in the FSM) that would clue the technician working on the vehicle to the other-than-standard bore diameters. This was also done for main and rod bearing sizes as well.
It's rare for this to happen nowadays, since the machining equipment at the factories generates MUCH more consistent dimensional parts.
Thank you for this. Now I know!
