Calculates out to 2170, but tire inflation affects tire diameter, too. The taller tires really make a difference!!

I suggest the 3.25 ratio. Will give you a hair more "dig" out of the hole. With Overdrive you can even go steeper in your choices. Just my two cents.

Ok so as life would have it this is the same third member I have under the coupe, who would of thought that I got lucky, but need to replace the pinion seal its starting to leak. Thinking that while its out put a traction lok in it. Need to look for new K-frame mods to see what it will take to put in a 700 4r, any particular year 700 r I should look for, and what is the differance from a 4L80, I know the E is electronic....
