Would it be possible to use the 130 tooth flywheel with the truck 4 speed? I know it's going to be tough to find another flywheel for that engine being that it's external balance.
Just buy a neutral balance flywheel and have the machine shop drill it out for the proper imbalance. The drawings are in the Moparts tech archive

That drawing is for 10.5" 130 tooth flywheel. Chrysler never used 11.0" 143 tooth wheel on the 340 cast crank engines. Will it work? I don't know.
I do know the location of the drilled balance holes on a 360 cast crank flywheel are different between the 130/143 tooth flywheels.
