It quite easy, You will need the yoke to go with it, I don`t remember if a 400 one will work, I don`t think so buT i Could be wrong. The Trans mount will be about 3 inches further back, Alls you should need to add is the bracket for the shift cable to the throttle linkage of the carb. Its a pretty easy swap, you should have no problems,
Oh!! The torque converter bolts are metric and no one ever seams to have them, So If you have a Tranny Shop close see if you can get them there or at the same place you get the converter. And be sure to make sure your starter will work, Depending on you Block modle you may need a different starter, The dust cover you have will fit perfect except maybe a little trimming around the Starter.
Thats the only issues I can think of but all in all, Its an easy fit
