The 8 1/4 thread

Gotcha, so he did the 2.45 gear? Shucks. I'm wanting to go from my 7&1/4 rear with 2.76s to something between a 3.55 and a 3.91. Was slow enough off the line before a stall, now it's even worse lol.

I'm 99% sure my casting number is 2852905.
So I just want to clarify, if mine is indeed the offset housing, I cannot get a shorter gear than 2.45?
