running hot
motor oil is designed to operate at 180+ so by removing the thermostat you reduce the lubrication. look it up if you doubt that.
for the thread starter... get a 180 thermostat, an HV water pump setup, a rebuilt radiator that doesnt have a bunch of sediment in the tubes, you will be good to go. get a water pump from hughes or mancini, for a radiator get a rebuilt/mopar one from radiators.com or someplace inexpensive. whatever size radiator you have now so that your shroud fits.
a clean radiator + good water pump = works wonders
