Not Ranked
I've never tried to fudge it, so I'm not sure on what you can get away with. The piston size wouldn't be the problem, but hanging the rings up on the block on the way down would be the issue.
I think 4.233" is true bore size for a standard 427, so that 4.232" compressor should put you in a good spot.
