I know this is an old post, but very interesting to me. I’d like to try a 400 with a long rod. What’s the big advantages to this besides fitment and maybe lower and mid rpm response? Always a student...
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.
