4.100s, 4.155-4.185 bore, and you can make 900 with that.

no problem fastcobra, I guess I should of been more specific and mentioned you might be interested in the rpm maxx rotating stuff as I understand they have one of the best int bal 4" cranks, I assume there 4.25" would be same quality. They got new H rods good for 1200hp, Lots of builders use there parts, good bang for the buck imo.

i prefer to stick with a 4" stroke, so the piston doesnt pull out of the bore at BDC so much. the further it comes out, the more wear on the piston and cylinder walls, and oil will get in the combustion. also, clearance to the pan rail, and cam to rod clearance becomes a big problem when you exceed 4". i suggest you build a 440, 4.185 X 4

do you think that 4 x 4.155 will be good for 900 hp, or very close ?

Inductions system (head, intake, exhaust, and carb) and valvetrain (cam, lifters, pushrods, rockers, springs retainers etc.) are going to have more to do with the power then the cubic inch. You could make 900hp at 400 ci if you have the right valvetrain and induction package

yes....and your heads certainly are good for that power. just need a good manifold to go with it along with the right cam. You could do an X351 manifold, those are one of the best single 4 manifolds that will fit.
