My '54 3104 has been converted to 12v. I put a 12v motor from a '60 Impala heater in my '54 Fresh Air heater. The squirrel cage in the '60 heater is smaller diameter than the '54 6v squirrel cage. I put the larger '54 cage onto the '60 motor - - it blows like a hurracane. Probably a lot more volume and velocity than the original blower. I assume that the 12v motor spins faster than the 6v motor. I hid an aftermarket 3-spd rotary 12v switch behind the dash with plenty of open space around it. I put an original style fan switch on the dash just for looks.
