Thank you @boominXplorer. That information will change my thought process for a solution then. I'm running into the upper limits of what I see as being comfortable or a safe margin of error with the cooling system now that I fixed the AC. The extra heat the AC adds in normal driving in these low 100 temps puts me around 210 to 220 for ect. I haven't checked it on a data log yet but I suspect it's higher than the gauge I have shows me it is. Prior to the AC fix I was running around 190 to 200 for ect. It's not even the hot part of the summer yet. On another note, my camshaft finally shipped. The driving force for the engine build will soon glare at me from a shelf every day until all the parts and heads are built/staged and ready to be installed.
