I would like to know if anyone has ever swapped a 94 300 with an earlier model say from 88 and how complicated was it. I would think it wouldn't be too difficult. what I want to do is take a 300 from a 5 speed 88 150 and put it in my 94 with the e4od I know the computer has to be changed but would much work have to be done as far as mechanical with the engine or electricalI know i would have to ad all the clutch stuff which wouldn't be that hard.
