Greg, are you using a stock ring and pinion with stock final drive...?

I have been considering a A,F,Ka,R,Z box for my 2056 build.

Anyone out there done this one?

Ka is a stock ZD flipped
R is a stock V flipped
Z is a stock N flipped.

this way I would not need to buy any gear sets...just use what is already in the tranny.

New motor should be good for about 6K rpms. maybe 6200. (IMG:style_emoticons/default/smile.gif)

with this box there would only be about a .4 gear ratio drop from 2nd to 3rd and 3rd to 4th.

here is a sheet with the stock vs custom gearing
