Running hot

Same problem with mine. Re-cored rad with 3 rows: no help. Fan shroud: no help. Spacer for stock fan to move closer to rad: no help. Thermostats of colder heat ranges: no help. Water Wetter: No help.
It would overheat after iding in traffic for 15 minutes. Taking it to the track was a joke with needing a 1/2 hour cool down AT LEAST between passes and running cold water over the engine and rad.
HOWEVER, I bought the M/P clutch fan kit thru Mancini Racing and PRESTO! No more over heating/running hot issues!! I can idle all day in traffic with no problem. I can make a pass at the track after a 10 minute cool down and watch the temp gauge go DOWN after 30 seconds of idling!! All that effort and money wasted chasing the wrong thing.
