1915 gearing ?

I think that the 3.88 final drive gear is pretty popular. As for changing the ratio you are running between 3rd and 4th I am not sure what ratios you would need to change to. Another thing to consider is what wheel size you have on your car as this changes drive ratios also. It slips my mind which direction your ratio goes as you increase/decrease wheel/tire diameter, sorry.
