67 Dart 273 timing issue

No No No. Leave the oil pump alone. The gear drives off the camshaft and turns the oil pump below and the distributor above. The distributor has to be timed with the camshaft. Simple as that. The oil pump doesn't have to be timed with anything. It is just driven by the hex on the end of the shaft.

Exactly, but I think what he is saying, is he gets the distributor slot where it needs to be, and it won't drop into the oil pump and stay lined up.
