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...
400 already has a great rod ratio, I don’t see an advantage myself.
They run real good when you put a 4.250 crank in one with some chevy rods and a 1.53 r/r. Doesn’t look good on paper but it works. I have a pump gas 400/511 that runs 10.90’s in street trim & 4000# in a b body.
