Brand New Built 302 overheating

[hassler]

Does it overheat at highway speed (45+mph) or just when you are at idle to or stop/go traffic?

Car is now fixed, flushed radiator, added stock clutch fan & custom shroud, 180° thermostat

I replaced my fan clutch w/ the heavy duty one. Its like a giant leaf blower in my garage, and cool sound

Thanks for posting the fix. I do have twin electric fans on my 82 Hotrod, but with a 150 amp alt. Last night I let it get to 220 w/o the fan on. After the first of four 1/8 mile runs, it cooled down and ran 180 all night.
