So I would like to throw out the following to the group for there ideas now,
as it could save me a lot of work.

Seawind with 20B radiator  mounted above the engine at about 20 degrees
above horizontal.  It can be tilted forward or back, but high in the back
(down flow) is the easiest from the cowling point of view.  About 450 sq in.
of surface area.

Front opening would start as a continuation of the spinner shape, about 18
inches wide circling the spinner (big frown) and about 6 inches high in the
center, slightly more as it follows the spinner outward.  The front edge
would just clear the prop.  Exit would be back past the high point in the
cowling, between large cowl flap and the continuation of the top of the
original structure.

A nose mounted upside down P-51 scoop?

What major rules am I violating here?  Better ideas are always appreciated!

Sounds OK to me Bob. What are the rads dimensions?

BTW how thick is the vertical-stab/engine-pylon?
That might be a good place for a rad on edge.
