I've heard that it is possible to swap the bellhousing on an A-727 tranny with one from a B-727 so that it will mate up with an RB motor. I'd like to get the group's thoughts about doing that instead of acquiring a push button B-727 tranny, as my A-727 has been recently rebuilt, has a Frank Lupo 2800 stall converter and a Transgo shift kit that I'd like to use. The motor will be a 413 that will hopefully produce around 500 HP. Thanks in advance, Brian Safford '62 Dart 440 4-door
