Chris, The validity of your reasoning depends on the air flow. If you
have enough air flow, you will have less heating of the air as it moves
through. I agree though that it is better to have a large frontal area.
On my TR3, I tried what everyone else has suggested. Finally, I
installed one of the commodity ($150) Chevy radiators. It has about 1
inch clearance on each side. I've run it in 100 degree heat with no
problems. I agree with what Bill says. When you have a large safety
margin you know something is wrong when you get overheating. When
racing, you have enough to worry about, so this eliminates one worry.
