I have a 79 with a 4l80e running 32" tires , the minimum gear ratio that I would use would be 4.10. If you are wanting a bit more giver..., I would definitely not hesitate to go 4.56. Currently I have 3.73's and spin 1850 at 60, that is a little low in my opinion, I for sure would take 4.10 in a heart beat.

So that in mind you have some numerical data to crunch to where you want to be gear wise.

The gear ratio you need will depend on your tire height.
If you need it assembled, PM me.
