The Stovebolt Site Forums The Shop Area Driveline 235 with a M-20 Muncie

I know that the 2 ring Saginaw 4 speed with the 3:11 first gear is the way to go with 3:55 rear gears. However I have a Muncie 2 ring M-20 with 2:52 first gear. Has any of you had this 4 speed behind a 235? If so what rear ratio did you use? I'm open to all ideas as to which rear end to use.
