I have a TKO 600 with .82 OD, but it revs too much on the highway, but then my motor has a big cam and does not like to cruise below 2200 RPM (but will pull from there) if I were to do it again, I would get a smaller cam so it would cruise easier below 2200 RPM and go with the .64 5th gear to get it to relax more on the highway.

I can send you the excel file for you to change the numbers to fit your application. (and so you can see it better, I was unable to attach a zip file or a pdf for some reason) Just PM me with your email address.
