Now I have about 21 square inches inlet to the Oil cooler. It looks like a
guppy. Mine is vertical, and Ed's is horizontal.  I have increased the air
to the oil cooler and removed the internal deflectors.  I also changed the
duct to bell shaped like you suggest.

I will also increase the water/Air inlet. You say about 60 sq. in. for both.

Now is the time to do all of this.  My engine will come back this week, I
hope.

So that is 120 square inches total for both water coolers right Jerry?
Each cowl cheek opening is about 6 by 10 inches is that correct?
I am just trying to picture this.
I think the oil cooler opening  may still be on the small side depending 
on how could the duct is. How big are your air outlets under the back 
bottom of the cowl? Is there a 3 inch or larger radius on the firewall
just above the air outlets?
