Can someone help me identify this 727? The number on the side looks to be: PK3736145 4940 0717? I purchased this with a 360 that has an emission sticker of Feb 1975. I plan to put it in my 73 Valiant down the road. I know that I will have to swap the tail housing and output shaft which is no problem as I will be tearing down the complete unit and rebuilding it. What I wanted to know is Other than the output shaft, housing and maybe the governor, is there anything else I may need to change?
