I agree. I found this out with my 427 Vette that has a fairly radical motor. I put a vacuum advance unit on it and the summer running temperature dropped 25 deg before my eyes immediately. With L-88 heads, 12 pistons and a 252 deg @ .050 mechanical cam it will start from cold and actually somewhat idle on the fast idle cam. Gas mileage - well that's another subject. I didn't get much positive feedback out of Keith Craft when I started to mention vacuum advance.
