If you are referring to a 235 pistons are available for a .080" overbore so if it will clean up at that size the block is usable and will have nearly 250 cid. Sleeving is only cost effective when the block casting number is significant which really doesn't apply here....If it's a boat anchor find a donor instead. If it will clean up stick a 261 cam, fresh bearings and dual exhaust on it to exploit the additional displacement.
