rear end ratios


rg lane

does anyone know or have access to mph per 1000rpm for various rear end ratios for a 90 6 speed?
Before doing my gear upgrade this is exactly what I did. Because I have an auto I loose some flexability. I plotted out the 2.59, 3.54, 3.75 both in Drive (1.0) and OD (0.7) to see how they look. Plugged the formula into Excel and then graphed it out. Then you can see the whole range.
