400, 440 stroker motor?

I've been out of game for a while and for possible engine combos for my 66 cuda. A few years back I was talking to a guy who said you could use a 400 crank in a 440 block or vise versa. Is that true and whats the set up?

Yup it's actually vise versa, you start with a 440 crank then you have to machine down the 440 crank journals to fit the 400 mains. 400 stroked to 451 is pretty common, These guys are one of top suppliers of stroker kits. http://www.440source.com/ also these guys to http://www.hughesengines.com/partResults.asp?eTypeID=14&pType=CK
