8 3/4 vs Dana 60

I am wondering would a 8 3/4 be able to handle 700 horsepower? I have a Dana 60 out of a 79 Dodge D-200 Army Issued and was thinking about rebuilding it and installing it in my Dart. My main question is can a 8 3/4 handle 700 horsepower and will it be cheaper than rebuilding the Dana 60. I would need to change the axles for 5 lug and thinking about switching to some 3.54 gears (I think thats the number but it might be off) and of course a posi unit installed. I would do about the same with the 8 3/4... mid 3 gears and posi. Try and help my uneducated self in this please. Remember MOPAR OR NO CAR and thank you very much!
