408 still overheating :/

Hey AJ,

I thought you had some holes cut in the back of your hood to vent the air out and keep fresh flowing through?

And BTW, the compression ratio thing is not that it is the cause per se, but it will create more heat that has to be managed. And AL heads will also take more heat out through the engine directly into the engine compartment than with iron heads, bypassing the heat flow path through the radiator. Turbos and headers also add more heat directly into the engine compartment that has to be gotten rid of and the regular cooling system can't do a thing about that.

From the symptoms described, it just sounds like things are getting heat soaked at a high temp.
