I posted earlier, the oil pump drive has nothing to do with timing, OTHER than you will end up with the no.1 wire in a tower "not specified" "by the book."
The pump drive "slot", with the timing marks at TDC, should point towards the front driver side intake manifold bolt. If it's wrong, just "walk" the gear up with a distributor and drop it back down.
BUT TO REPEAT, that will NOT cause this problem. If you have the distributor and plug wires in a position where you have room to "swing" the dist, and can set the timing, then the intermediate shaft is no issue.
