8 3/4 strength before breaking ?

[actionange1]

Which center section do you have? Aluminum or stock? Great looking car my man!

Stock 742 case with stock caps.
Guess I'm living right with the longevity factor...:icon_thumright:

It will break simultaneously upon reaching catastrophic failure. :sFun_doh2:

Seriously, there is no way to accurately answer this question as there are too many variables, but an 8 3/4 will withstand a tremendous amount of abuse. I would run the 8 3/4 and start a Dana fund if you're afraid of it, then if she ever breaks then you've got it covered, if she doesn't, then you've got mad money for something else.

And there will be something else ... ;)

When we started running low 11's with a 4 speed car that weighed 3200, we started shaving ring gear teeth at the launch but we were launching at 5000+ rpm.
