In most "dreams" they will go that far. Not usually, it's very rare and you'd have to have it sonic mapped to see first. ALOT of guys try to make 428's out of 390's and they tout they are wonderful. They are JUNK......and time bombs. One in a million 390 blocks will have the wall thickness to safely go that far, as core shift makes them very thin and to get all 8 cyls in good shape is hard to do.
