3.6 in A-body

Currently an 8-1/4 with 4.56:1. It was already in the axel when I got it and I thought its help up the low end torque. But with my T5 2.95 1st gear, it makes for a 13.4 overall gear ratio, so 1st gear is pretty much useless. So I'm thinking about stepping down to a 3.91
good idea. 3.91 or even 3.55.
