What is the best, strongest 8 3/4 housing?

Yes Mark, It's OK. That case works fine for what you are planning.

I'll happily take all those junk, weak sauce 741's with the equally junk cone sure grips since they are worthless... LOL

Each of the cases have a weak point in original pinion design.

Unless you are dead hooking a big HP car that weighs a bunch, any 8.75 rear is good. And when you get to that point, there isn't a 8.75 that will live in that environment for long.
