no, because the heat energy your cooling system is absorbing is the same energy used to push on your pistons

When you pulled out the first two rads did you not notice the circular shaped pattern that the fan would leave then? I do find that quite odd.

This is why I don't like the stock fan and ditch every single one I come across for a dual electric setup. Same thing must have happened to my car, the fan was all chewed up and the fan shroud was mounted in a weird spot with new holes drilled.

And on the subject of thermostats, as long as you are not putting the ECM into a cold start state, there is no reason to not run the engine at a lower temp. The only reason the factory does it is to meet emissions standards. I have been running my Caprice at 160deg.F for years and currently get 25MPG average with a 350ci LT1 and a 4000lb curb weight. A cooler engine means you can really max out that ign. curve for max VE and more torque.

EXACTLY! That's what I thought. You're 'robbing' heat that makes power, but you're also reducing the possibility of detonation or knocking, which now allows you to get more aggressive on your mapping and therefore make more power (at a lower efficiency).
That's my brainfart anyway...
