I'm looking at the Chrysler parts manual. All the 383HP/440HP B Body and bigger cars came with the 093. The Valiant/Barracuda/Dart with 383 4 BBL came with an 091 in them. It was considered an A727B as was the 093 trans. They do not show a 383HP or 440HP listing for an A Body? Only a 383 4 BBL. They just say that the Satellite/Coronet w/383HP and 440HP eng, the Chrysler w/440 HP and the Ply/Dodge except SW w/440 and HP engines had the A727B p/n 2892093. It seems like the M code should have had an 093 in it because it was behind a 440HP?
