Worth a try, Fred. The biggest problem with using pans for high-level cooling 
is IMHO, the flow of oil at the pan walls is relatively stagnant and is made 
worse by the oil in actual contact with the pan being cooler and more 
viscous, so the layer tends to stay there rather than circulating. The cool 
oil then insulates the rest... I used to mess around with air-cooled engines 
and this seemed to be the main limiting factor. Oil doesn't give up heat very 
well; it'll take some tricky designing to get this to work well, along with 
the present baffles and doors etc, but if it can be done, it sure saves 
adding in vulnerable big, long oil lines to an external cooler. My own 
"research" if you can call it that, shows that at "reasonable speeds" 
(e.g-under 120mph), oil temps and water temps are very close together. Its 
only when you start pushing the envelope that oil temps get outa hand.
