what rear would you go with

This is a show car only. It will never see a strip. It is mainly for cruise ins, car shows, maybe wiping a chevy or fords a*s once in awhile. I just wanted to know if I went and put a 3:55 or maybe my 3:23 in it if it would serve as toilet paper. I am not too familiar with these gears. I can tell you that the 3:91 I have in it will just light up the street.I am just looking for an all around good rear to maybe get on the interstate if I wanted and travel a little without being drounded out inside the car.
