can't quite understand what you mean by spin the timing marks out. As far as timing goes, there was a service buliten to set timimg on all 3.7 motors to 4 degrees btdc

If I understand you correctly, NO, it is not common for the harmonic balancer to spin. The balancer is made up of several parts. The inner circle with the crank shaft hole, the leather hub packing and the outer ring. Not sure of the proper names for them, so those are just my descriptions... but the outer ring on the balancer is wedged to the inner ring (like a prop hub) by the packing and should not be able to spin without the entire unit turning.
