Sure. The overheating problem has an ultimate solution. We've tried 
the usual list of water wetter, better ducting, better pumps, and all 
that stuff and never was able to make much of an improvement.

The real solution is to convert to an aluminum Ford- or Chevy style 
radiator. Even full of coolant, it weighs a lot less than a stock 
copper radiator. And it's cheap! You can get one of these radiators 
for under $200. It takes replumbing, which is easy, and mounting, 
which isn't too hard, and a re-do of your ducting. I have to use a 
thermostat to keep the engine hot enough. This radiator is much wider 
than the stock one so it presents a bigger area to the incoming air.

I don't have pictures on a website, but I'll send you pictures of 
mine if you want to see how I did it.
