Harmonic balancers and belt width

[Bobacuda]

I am in the process of rebuilding an engine out of a '47 Dodge car for my '53 Dodge truck. The engine from the '47 does not have any numbers on the top left side of the block to identify it with.

The engine from the '53 used the narrow belt and a "normal" looking harmonic balancer/belt pulley. The '47 uses large harmonic balancer that is a separate piece from the pulley. I can't recall ever seeing the setup the '47 engine has before.

My question is this,"Is it OK to remove the large hamonic balancer and wide belt pulley and replace them with the "normal" looking harmonic balancer/puller off of the '53 engine?" My current generator uses the narrow belt and if I convert to 12V I will want the narrow belt.

Sorry for the short notice, but the engine goes to the machine shop tomorrow. Thanks for all of your help.

I don't believe the trucks used a harmonic balancer, just a pulley, unless they changed it in '53. I see no reason why you couldn't use your truck's pulley on the car engine. It shouldn't cause any problems.

I have a 53 motor that came from ( Buds-truck) that has pully only no balancer, narrow belt.
