Re: Use stock crank damper when rebuild?
Stock 5.0 HO balancers are 50 oz. Getting the assy balanced would be best done with the balancer and flywheel you plan to use. Otherwise they will use standard units for the job.
If you are replacing the crank etc you can get a different balance weight like 28 oz or even go with internal balance. The heavier external balance puts more stress on the bearings with all else being equal.
