Running without thermostat

jrgoffin · 07-16-2005, 10:05 PM

I run a three-row radiator, stock fan and HD clutch and use a 195 stat (the good brass ones) and never run hot, even with the a/c blasting. My temp probe for the mechanical guauge is in the water neck and I'm always at 190. It probably helps to have the '93 Cobra pulleys or the factory pulleys, since most cars run hotter with under-drives since the water is not flowing as well.

I live in South Florida and I don't run a thermostat, but I do have a restrictor. I run 185 running around town. Being in stop and go traffic for a long time the temp will jump up to 210-215. I have an aluminum radiator with a proform electric fan. That fans just isn't cutting it. It kept my little 302 cool, but not the 351. I just order a DCC 18" fan kit. It pull twice as much CFM. It should do the trick.
