Better question for Brent. I've always heard that side oilers were pretty thin wall casting, in part due to their original 4.23 inch bore to start with. I've heard .020 is safe, .030 good idea to sonic check first; anything over .030 need to be very careful.
A 428 block typically had a little more meat around the bores and could typically take a pretty good overbore, although all of these old production line blocks were subject to potential core shift.
I heard it all on Al Gore's internet - it must be true.
