8.75 durability for big block street/ Strip

That is right on the fringe, so better to go Dana to be safe. That said, my car has had and 8 3/4 under it for over 27 years. A few years back I had to get a new housing (the fabricated MO875 from Moser) because my Caltracs crushed the axle tubes, but besides that, I have used the same pumpkin and gears for ~ 18 years. It is a 742 case with Moser 35 spline axles and a spool with 4.10 gears. My car is 3250 lbs and ran high to mid 10's for most of that time (foot brake). Now the car runs low 10's, but since I still foot brake it lives on....If I were to ever switch to a T-brake I would Definitely go to a Dana FIRST.
