Not trying to thread jack but I'm in the same position as the OP, rear end options.
606tq/569hp 462ci on 295/55/50 possible 295/65/15
I've got the 69 XH nodular rear with 3.55, part of me wants to upgrade this since..
I've got rear disk brakes on it already.
This rear end is factory and nice, I'm not dragging the car but at 4000lbs and possible 30" Street R tire to hook, it'll get some abuse.
What if me and the OP wanna keep the 8.2...
Moser 31 spline and what new gears etc, can the 8.2 handle the torque and occasional street launch for us???
I'm thinking it can and if we update the parts with only the level of hooking the tq comes into the equation. Street tires add no real load on the rear end but dead hooking is now a big change, 30" x 12" Street R tire.
Thanks and sorry OP if this Jack's your posts.
