727 poly engine transmission

we only cared about the trans Interchange. So what if this happens to be an A body site? The gentleman asked a question. I could mention even more engines, but why? Yes I had a Chrysler 303 55' and yes the newer trans works, sorry. I/ve only owned them for 40 years. my nephew recently put a 71'340 in a 60' dodge truck using the had the original 318 and four speed. He used the original bell housing and flywheel. Clear as day, maybe you should work on presenting a little more civil post.
