im rebuilding a gen 6 454 for a friends boat and need a recomended oil pump and pickup for the stock 9inch deep pan anyone have an idea or part #

As far as a pump goes, I would use Mellings 10778 or 10778C pump. Personally, I use the 10778C. However, some prefer the 10778. Its up to the individual.
There are too many pickups out there. You have to match up what you have. Cant offer any help there.
