I don't argue that the 8 3/4 can take that kind of power and have witnessed them hold up really well but certainly the dana will handle it better.  Now that you know what gave way, get some better axels and go from there!  Good luck!

Just got off the phone with Dr diff
He said if I put the stronger axle in, I'll break it again or damage the position unit
It might break the first time back at the strip he said.  Seen it many times.  Said get the Dana or don't hard launch if I take to the strip, slip the clutch some.   Have to think about this a little more

He would know.
