The 390's bore is 4.05, the 428's is 4.13. A few blocks will bore out the additional 0.080 but not always and certainly not always on 8 cylinders.

Have the engine sonic checked so you know that you have enough wall thickness to support the bore you want. Anything else is just a waste of time and money.
