Will a Stock 489 handle 700hp?

Yeah, I was going to run a 8.75 But future plans of t-brake made me buy a Dana.
I do wonder though if guys are welding the back brace on without any sort of help to keep it from warping, I'd use a jig to tie the housing studs and ends together maybe along with the mittler narrowing jig. Just a thought.

the brace has to be welded in completely, then the bearing collars installed. A good friend of mine just did one for another Stocker 6 months ago.
70aarcuda is right about the weak link. It is an eventuality. But for guys in Stock, they have to run what was in the option list. An 8 3/4.
Bracket racing, it's not much of an issue. Make up for it in the dial.
