Do you already have the transmission?

Yes I already have the trans.

I'm thinking a 3.70 or 4.11? With a 3.70 at 1800rpms I'm cruising at around 75 in 6th;
With a 4:11 at 2000 rpms I'm cruising 75.
3:70 at 6500 in 4th gear Im going 135, 4:11 is 121 which is around what the car should trap in the 1320.
