milodon oil pump and external oiling questions.

I am in the process of gathering the smaller bits for my new stroker build. I am looking into oiling now. I will be running the milodon road race oil pan. they offer the pan with a built in pickup with screen and external oil port. I like this idea because i can use the larger dia. 12AN hose and get more supply volume to the pump.

I like these two pieces.

Milodon Billet Aluminum Big Block Chrysler Oil Pumps 21814



and the cover with the rear facing inlet.



do i then just put a pipe plug in the internal pick up tube port in the bottom of the block?

what about oil drain back? would the filter be sufficient in holding oil in the pump?
