That noted, if you have a pair of 6X-8's or 5C-7 or 5C-8 heads (with near 100cc chambers), they would be better suited to 4.25" stroke build in a 400 block.

I have the time to find either 4's or 8's, so I just wondered which would be a better starting point. Looks like most of Butlers stroker kits are 4.25 cranks so thats likely where I would end up.
