I know this has been covered before and I have read the archives, but yet I am experiencing what I believe to be higher than normal operating temps on my 396. even @ a cool (south Florida) 65o, my 396 runs from 200 to 220 degrees. I have brand new "nice" everything in the cooling system including a three core radiator (stock). I've replaced or tried everything twice so I know it's not a "parts" problem. No blown head gasket either. Is this normal? what temps does anyone else out there see @ 65 degrees? Would a 4 core radiator help? I'm really concerned because come summer I'll see 95 degrees plus the AC will be on!
