To go big in this instance the best way is to replace the 4.00 stroke 428 crank with a 4.21 stroke 455 crank or perhaps a 4.25 aftermarket crank.
Boring your 428 to the max while keeping the stock 4.00 crank gets you 440 cubic inches at most at .060 over, so only 12 cubes gained by maxing out the bore.
Going to the 455 crank gets you 455 cubes at a reasonable .030 bore or 462 at .060 over on a 428 block.
Again, I would never bore any block to the maximum size unless absolutely necessary.

Good to know, in order to make an intelligent decision.
Be aware, see my last Thread: "Th 400 Pontiac Transmission build or not to build myself", see # 96-110 posts, that I accidentally posted there, they should be here.
Also, in the past the posts that I have been involved in, whether I originated them or just were involved in, used to post to my email, they are "not" today, I want to know why? Moderator, please look into the reason for that.
