Paul, a few weeks ago, you mentioned the possibility of making the
oil pan 1/2 inch deeper to allow the use of the stock oil pickup
without modification. Did you ever have a chance to look at this in
Rhino? I have set my rad under the engine where I think it should
go and there is about inch clearance between the bottom of the oil
pickup and the rad. Does this leave enough room for the intake
plenum at that point. You can ignore the rad inlet and outlet as
shown in the photos. I am going to cut them off and replace with AN
facing backward not up.
Also, although I have perfectly good Mazda oil cooler, I am having
trouble finding a place for it. I am leaning toward two cheek oil
coolers at this time.

As I recall your rad core is 13 by 16 so you will need a minimum of 25%
of that area for the entrance wedge duct. That will be 52 square
inches. Divide that by 13 and you get a minimum clearance
between the rad and the motor plate of four inches.
I would use the stock cooler mounted along the inside of the right
side cowl with a direct dump to the outside of the cowl.
Since the stock oil cooler core is about 18 by 4.5 more or less
you will need a wedge duct with about a 20 square inches
opening. With a cheek opening on the right side of the front
of the cowl about a five inch diameter circle is about right.
The oil cooler duct can then transition from the five inch
round to a 4.5 by 4.5 square opening feeding the oil cooler wedge.
