A little clarity ,
The center pic in post 7 shows a stock 33 motor with the right oil pump and NOS drain pipe .
Good idea to use one .

The use of 33-34 oil pans on 35-36 blocks is common and does not cause problems if done right .
That equates to not having the breather pipe under the fuel pump stand .

Isn't the oil cap on 35's an air scoop ?

The oil pump drive gear cover gasket can cause your issue also .

The reason I asked for the spacing on the main studs is that will tell us if it is babbit or insert mains .
No shims on babbit mains .

Simple way to check for excessive rear main clearance is GENTLY jack up on the flywheel and see how much movement you get .
Simply hold something against the crank and main cap in the up position and let it down . Crude but it should work .

Let us know on the breather tube and oil drainback tube .
This is first order of business here .
