73' B3 340 Duster pro touring build

Hey 76Orange, Are you saying a new motor will fit in the place of the old motor for my Duster on the outside. And if you are what motor is it.

I already did my firewall work and do not mind the motor on the engine side if it looks good, or new style.

Actually the motor on the truck lays the wrong way to fit in the factory location on the A body, but the adapter plate bolts to the triangular bolt pattern.I dont know what motor would work, maybe the FMJ mentioned in a earlier post would, I got the adapter from the Dodge dealer for a early 90's Full size truck.
