The first radiator was a 18"x 19" frontal cooling area and had double one
inch core, but had excess of cooling capacity. The second one was 6"x21"

with

two rows of 1 1/2" cores  and 2" tanks at both ends. The coolant inlet and
outlets are 1 1/2" and 1 3/4" in diam. respectively.
The front of the scoop is angled at 35-35 degrees.

On additional thought from the looks of the front picture not enough
attention was payed to the contours of the internal diffuser. The
outside of the scoop looks great however.

Here is a picture of the exit flap. This too is also very well done
but the over all result is one of the reasons I tried to get thin
angled rads inside cowls to work to reduce the drag penality from
this kind of installation.

 Wouldnt you think that from a drag perspective the appropriate thing to do
would have been to stick with the original radiator and reduce the airflow
through the cooling system? Is this too obvious? As long as you have the
space, the water pump capacity, and can stand the weight is it possible to
have too much radiator?
What am I missing here?

I would think so too Mike. This adds almost a foot of frontal area
and giving it the benefit of the doubt a C sub d of 0.2 that is
20 pounds of drag at 200 MPH or about 300 FPS. That is about 11 HP at
200 MPH plus what ever it takes to jam air through a 3 inch rad.
