It's surprising that the oil pump drive shaft hasn't twisted itself into a pretzel yet. Your worn distributor gear is proof of excessive oil pressure and drag on the pump. There is no need for a HV oil pump in a SBF except in a highly modified engine with appropriate clearances. Stay with 10W30 or 15W40 max. Anything thicker than that robs power and does nothing for the engine. Replace your distributor gear with a steel gear (not cast iron) that is compatible with your roller cam.
