400 builds-anybody?? NON STROKER!

I did a 400 with a 383 forged crank, Hemi rods and shelf pistons a few years back. Worked great for what it was. I don't think I'd bother doing it again but it is certainly possible to build something like that if you're willing to track down the various parts.
Andy, what was the advantage to that combo? Or was it just an experiment to see what it would do? I’ve noticed you do a lot of builds. Then share your info on here.
