Will a Stock 489 handle 700hp?

You can get a Dana 60, brand new for $3k. I found them online. I paid $2k for a piece of crap 8-3/4 from someone in this forum. It eats pumpkin for lunch. If you have the choice, I would definitely go with the Dana. And I will never spend more than say a couple hundred bucks buying anything in this forum again. A $2k burn sizzles a long time.
I know it wasn't one of mine I built, cause I never heard anything about it.
