well its said that the 400 is the strongest factory bb ( excluding the hemi ) and from the pictures ive seen on the web and my 400 seems beefier than most 440 and 383 blocks ive seen bare.
not trying to argue or anything just trying to help so you have a cheaper piston choice and dont have to go custom, and those 27+ ci are a plus to me.
this article its interesting

at least it helped me to clear some big block myths like the thin castings and the earlier the better it is.
you have a great proyect btw !
