Eaton posi 8.2 10 bolt?

I want to put an eaton posi in my 65 el camino rear end am I correct that it is an 8.2 10 bolt for 65? It is going to have a zz430 clone with a pg behind it the crate engine manufacturer suggests 3.70 gear ratio will this work for street driven daily driver with minimal freeway usage?

You have the 8.2" 10-bolt rear end, providing it's original. A 3.73 rear gear wouldn't be bad if you avoided long trips on the interstate a lot (like you plan to do), IMHO.

You already know a TH350 would be a move in the right direction, I'm sure- so I'll leave that alone.
