408 vs. 440: Which Would You Choose?

I appreciate the responses, everyone. Sorry it took so long to respond; got busy with work once again.

DA4AD made some excellent points about the modern characteristics of the 5.9, but that said I'm leading towards building the 440 since it looks like it'd be cheaper to build than a 408 as everything else is a wash.

I don't want to touch the short block of the 5.9 I have now so I'd have to buy another engine to stroke... I'm looking at about 6k-7k to build a 408.

I think I can rebuild the 440 for cheaper than that, especially since I can run stock heads.
