I have a 440 and 727 transmission I want to put in my 91 swb 3.9 V6’s truck. Any idea on what problem I may Encounter
Fourth gear is overdrive, The 727 doesn't have it. If you do it put a spread bore carb on it. Depending on how you plan on driving it you could put a A518 in it.Friend of mine runs a 413 in his 1956 Ram with a 4 speed, it hauls azz and gets 21 mpg!
