Dana or 8 3/4?!? Need opinions

I personally dont think you NEED a dana, but imo if your going to have build one up from scratch, id just go all the way to a dana...an 8-3/4 would last quite a while behind an auto (although some will tell you otherwise...opinions are like a-holes rite) i think your need for speed is only going to ever progress in the future, and with a dana under the car your done having to worry about that part of the driveline for pretty much forever lol...the price difference between the two is too little imo to stil build the 8-3/4 (wish i had done a dana in the first place)...also i havent heard of guys having trouble with the gas tank, only with the rear end moved back have i heard that...is your rear in the stock location or moved back some?
