Okay Matt -- just for you - I disassembled the pan so I could get better measurements and better shots for what's inside….
The BAFFLE HOLES are .250" (1/4") off the bottom -- so it takes 1/4" of oil to get to the bottom of the holes…. or thinking of it a better way -- there's always going to be 1/4" of oil in the little sump box.
The FLAPPER DOORS only open to the inside to let oil IN the book -- and they're also .250" off the bottom -- so the flaps are just right at the bottom of the holes.
The box is basically just creating a sump for the pick up…. I haven't dropped the pan to see what size the pick up is so I don't know how much room they're left "around" the pick up. My guess is 1/2 to 1" on all sides.
Trap doors are on the INSIDE of the "sump box" and only open inwards
