Hot Rods 1941 plymouth transmisson problem

Discussion in 'The Hokey Ass Message Board' started by bennyruizbad1941coupe, Jun 12, 2020.

  1. I am doing an engine swap on my 1941 Plymouth coupe, the original flathead six is I believe a 201, could not decipher engine numbers N477 ?? I am installing a D34 230 Dodge flathead six that came out of a Dodge Coronet with a automatic transmission. The original block crank has four studs for the flywheel, the replacement engine crank has eight holes for the original automatic. I cannot figure out what flywheel to get to continue using my 3 speed transmission, current flywheel will not line up with any of the holes, lines up with three , but not four. Any ideas I what I can do ?

    All I can tell you is about manual tranny's, the 8 bolt crank vs 4 bolt crank use a different flywheel offset, I'm almost sure I could have bolted either on to either (been years) but flywheel sat closer to engine on one of them when trying to mix and match.

    I think I still have one of each flywheels here, but for manual, not a fexplate (if MOPAR used that).
