ok i have a cooling issue i cant figure out. stock 350 chevy that was in my s-10 and ran 180-190 all the time no matter what. i took that motor and put it in my rx7 and the only thing different is i put an electric water on (new) and used the alum radiator that was made for the car. i tried one of those restrictor plate in the thernostat housing so i thought it might be the wrong size so i put a 160 thermostat in it and still the same thing 225-230 degrees. any ideas? its even the same auto meter temp gauge.
