I was swapping my oil pan from a Moroso 7 qt to a Hemi 6 qt and my new oil pickup tube is too small. Turns out, my 440 block was drilled and tapped to accept a 1/2 inch oil pickup tube which is what I had on there apparently.

My 440 is very mild, Edelbrock heads, stock sixpack pistons, a MP 484 cam and headers. Do I really need to run the 1/2 pickup on this motor or can I simply get a bushing/reducer and use the 3/8 pickup? I assume I would need to trial/error the height to make sure it sits properly on the bottom of the pan first.

Has anyone done this before?
