I was at a friends shop who does work on about a 1.2 dozen local guys Trifives today and he had this Evans antifreeze replacement. You use it straight at 50 dollars per gallon. Customer is complaining that his 355 with hump heads runs 200 degrees in summer with AC. Car has one of those cheap chrome blade blue flex fans and electric fan behind radiator. Rad is in 6 cyl position. I said get a decent engine fan and build a nice shroud and forget the Evans stuff. Anyone ever use this stuff.
