It could be a gearing issue - differences in pulley sizes might mean the alternator is spinning slower at idle that it is supposed to.

Does the voltage come up when the engine speed increases?

Where did the 120A alternator come from?

Right pulley for which application? 80 series cruiser, or the 5 litre donor vehicle?
