8.75 durability for big block street/ Strip

I was going to say that you are on the ragged edge of an 8 3/4 with 600hp, and that the light weight helps. Then I saw this post .

Good idea, i forgot to mention I will be having a 2 step & most likely a trans brake.
Thanks

In that case I will give three choices.
A. Dana 60
B. Dana 60
C. Dana 60.
Edit: forgot to mention: a body 8 3/4 in good shape is very expensive, selling yours might cover half of a strange 60. If you bust it into a bunch of little pieces.....not so much.
