I think the roller motors came out around '85-'86. You will need to change out the balancer and flywheel from 50oz to 28oz. It wouldn't hurt to balance the rotating assembly. Need to change the gear on distributor if using the your stock ignition.(I am basing this off my '78 ignition,it should be the same) Are you using the serpentine belt drive or keeping what you have? I would price it both ways- rebuilding what you already have and build it to your liking, and rebuilding the roller with the changes. If you buy a used motor and drop it in, you never know how long it will last.
