Tire Size Opinions

Someone who has been rodding a bunch of mopars for many years told me a 255/60R15 with 3.73 gears would be best with a tunnel ram, but that was with dual Holley 600s.

I'm not sure if that advice is good, or would be different with the efi.

I also heard a small tire is best for a tunnel ram, but I think that logic is based on the tr liking a higher rpm, and getting the tires moving, something, something.

With the efi though, the get up and go comes on quick and strong.
