so I been looking at some threads on this. So what is your take on this. This will be for a 360 pushing around 400+hp. Now if I go with a 727 will my driveshaft be to small since I have a 904 ?If you have a built 904 did you change to a bolt in sprag? Change the front cluth retainer drum? I planned on putting in the wider band 1.75 which was standard for a 904/ 360 and changing the 1st gear to 2.74. I know the torque converter would also have to be changed, Not planning on racing but will be changing tires often. Tires are not allowed to dry rot on Mopars LOL Thanks to all Dave
