10's on $5,000 ?

If I did a big block I would stroke a 440 hands down no question...
Just curious, what C.I. would you look for, and why not the 400?
For me, the "B" engines are about 50 lbs lighter, offer more room for headers, and you can yawn and get a 499 C.I. stroker kit for about 2200 bucks for the 400. Besides, the 400 has a starting bigger bore than a 440
