Re: 345 to 392

No.

The 345 and 392 are supposed to have different castings. You might try to
overbore it, but my guess would be super thin cylinder walls and all of the
overheating/piston wear problems associated with it.
All of the C.I. gain from 345 to 392 is in bore. So there isn't a "stroker"
345 option either.
