I was planning on using a 1970 rebuilt truck 727 behind the 1965 273 I just finished, if I end up dropping it in a 1961 D100 shorty. I read a post here recently saying that the early 273 will not take a later model auto trans. Any help here? Chris.
Good morning Chris
I believe someone with more expertise should reply soon but I think the issue you will need to address is the converter snout that registers in the crankshaft. I believe the 273 has a smaller diameter. You will need a special converter I believe. Maybe a search on here will gather more info. Good luck
