Rear gear help

I have 3:23s in my barracuda and like them... it is not the quickest thing around but I think that is my tired 360 and going through 2" pipes and mufflers (never changed from the 318 that was in it). I did have 3:91s in it but did not like them, I went through the gears to quick and it did not seem to pull as hard... I would drive it with the 3:23s in it and see how you like it.
