Poll-which rear end?

To me this is yesterday's poll because everyone would be using a 904 or 727 transmission ( Non overdrive ) with it's first gear ratio of 2:45 and would need 3:55 just for the street and highway / or 3:91 for street and race with bigger tires...
Might be Yesterday's Poll but it's Today's Decision for me as I'm not running an auto. Just trying to pick the right combo for my proposed build
