400BB Engine

I agree, a stroker is agood idea, and can be based on factory 440 parts. But you really want to talk to a Mopar friendly machine shop first. I build a decent amount of engines. I've found it much easier to let the shop doing the work advise me, and in many cases buy the parts for me. I pay a little more, but if something is boxed wrong or the wrong type or size, it's their problem, not mine. If you want to buy all your own parts, have everything measured BEFORE you place any order.
