I am not sure if one is "better" than the other. I guess it would depend on the application. The M-20 is a wide ratio transmission
which means it has a lower ratio first gear, (I believe that it is 2:52 to 1) which will give you greater starting torque. The M-21 is a close ratio transmission and has a higher ratio first gear, 2:20 to 1. Outside of the different first gear ratios the two transmissions are very similiar. Here is a link that has more information on the Muncies. Jim http://www.gearzone.net/kit.htm |
