Jim,
I not only saw Ol' Yeller :) at the last TWO V8 Meets, you let me drive her
back from breakfast. Good thing I didn't have too much coffee!
I also remember the cooling holes in the fenderwells that the headers pass
thru. It has often been mentioned that getting the heat out of the bay is
the key. Which, I happen to believe that my driven fan does. Ceramic coating
of headers, yes, is a proven help.
The horsepower loss? What are we really talking here, 2-4 HP? And, sorry
James, I can't agree with the statement about going electric fan "lessens
noise". Some of the high CFM electric fans (which is what is needed) sound
like a Hoover when they come on. :)
Carl
Stock rad, block huggers, driven fan....no overheating.
