John, the difference lies in whether the oil pump is driven by the cam and in turn drives the distributor, or visa versa. In your case the camshaft drives the oil pump which in turn drives the distributor. Thus you can't use a drill to spin the oil pump.

Another alternative to pre-oiling is to attach a small reservoir of oil to the main galley inlet and then pump or use compressed air to flood the engine with oil.

One thing I would strongly recommend before starting an engine which has an unknown history and long storage is to drop and clean the oil pump and especially the oil pump suction inlet screen.
