3 speed manual and 2.76 gears with /6

Humm.... A lot to think about. It has 3.91 and A 745 in it now. Highway speeds are a no no. I found a 3.23 and 3.55 today. Im considering a build of a 360 and 904. Which one with that combo? I know it's not an Abody but y'all are the go people. Thanks.

I also have a 2.94 I could take out of the Dart. Not sure how much it matters on tire sizes but, I'll probably run a 27-28 tire like a 215/75/15. Here is a progress picture for those interested in trucks.
