Oh, by the way, bite me!

I guess no one forgot to take their azzhole pill today...

GM's research was specifically to address coolant issues with high horsepower engines being developed for the Corvette. (not that high horsepower engines have anything to do with Cobra's) Since emissions dictate not running rich (which would lower detonation problems) they addressed the "real" problem: the steam pockets that develop in any engine's coolant passenges above the cumbustion chamber. (turns out steam is a lousy conductor of heat, go figure) The problems you stated ie: valve spring fatigue and cylinder bore wear are a direct result of combustion chamber temps, not block temp.

There is a huge difference in your cumbustion chamber temp and your coolant temp. Why do you think your recovery tank level varies so much between hot and cold (the liquid coolant only expands slightly) that's how much steam is in your cylinder heads and upper block.

I dont think it would have helped you Ronbo....
