I can tell you a EWAG (Educated Wild A$$ Guess) or probably just a WAG way of telling. Lift the rear off the ground & rotate a tire one complete turn and count the rotations of the drive shaft and keep track at the end. Three & 1/4 turns is 3.23. Three & 1/2 turns is 3.55. Four & 1/2 is 4.56 and so on and so on! I hope this helps. Unless it has been worked on or rusted off, it should have a tag on it somewhere with the ratio on it.

I can't find anything about that on the window sticker, build-sheet, tag, etc. It seems like it is around 3:00, and I am sure they didn't have many choices in the mundane 383 2 bbl.
