8 3/4 Diff strengths?

I know of a couple high 9 sec A-bodies running 8-3/4s at the track, but I've also seen a couple break in high 11 sec cars though too. Waaaayyy too many variables to put a HP limit on them.

Hell, I know it's apples to oranges, but my late uncles 7.60 FED ran an 8-3/4. Many old FEDs and fuel altereds did back in the day. Of course they don't weight anything though. Like I said- waaayyy too many variables.
