Build or buy 408?

I build all my stuff and have a machine shop that I trust. As mentioned when you build your own you know exactly what's in it and you can build it exactly like you want. IMO before you order the first part you need sit down and decide what your expectations are, then talk to people who have built and ran these engines to see what you need. I don't put much stock in computer programs predictions, I'd rather talk to peoples who have been there and done that.

I recommend Dave Hughes a lot, he's always been helpful and has years of experience building Chrysler engines. Plus, his cams have ran hard in everything I've put them in.
