I run an 8-3/4 that has held up so far to the punishment I give it. Car is SB auto that runs mid 10's and high 1.4X 60'. But with this being right in that zone where it may last and it may not, a deal came along on a Dana 60 and I'm swapping it out. At least now I can put some more power to the car in the future if I want to and not worry about the rear blowing apart. This Dana I bought has been low 8's in the previous car so I think I'll have plenty of room for improvement there lol.
