A727 transmission questions

[1969CoronetR/T]

What models and years used the A727 TorqueFlite? Can a big block converter be installed in a small block A727?

there were literally millions of them made through a vast production year run. the main difference between SB and BB is the "bellhousing" . with the correct spline count on the input shaft / converter, and weights (if applicable) and correct flexplate . yes .

here is a little info, pay attention to lock up vs non lock up
