Ford boxes are usually in the region of .87 for 5th gear, so a diff ratio of 3.6 ish is ok. If your box is direct top then you would be looking for a diff ratio of around 3.1 For your box google with all the details would be a good place to start, alternatively find a way of turning the input shaft and see what the output does.
