1964 Dart 4 speed with overdrive

I'm running 3.55 gears in the rear right now, after the swap I might run 3.91 also have 9:5 compression headers 473 lift cam on 256 duration Howard's. I currently have the 64-65 four speed with cast iron bell housing.

Actually when I'm lazy I shift from 1st to 3rd then fourth. When I'm really lazy I go from 1st to 4th lol.
