Cost for A Body 8.75 Rear End

Oh I’m sure I won’t get away with a full rear end without dropping some decent coin. I just want to make it bulletproof so I won’t have to worry about it again. I have no plans on tracking this car at the moment but who knows 10 years down the road. Just future proofing
Yes, I understand. Trying to guess what the future will bring is kinda like bathing a cat.
I swapped out a 8-1/4 rear to the 8-3/4 for one reason- i can change gears very easily. The 3.23 sg will be way better than the 2.45 - 8-1/4 rear with a ratchet locker I built. It was only for the engine break in. After breaking in the engine it was kinda of a slug and needed more take off umpf. So I went 8-3/4 BUT If I decide to run at track I can drop in a set of lower gears if I want or go backwards to 2.76 if I chose. Very easily too now. It's just a lot of money for that option. Great luck with your path. I wish you the best.
