I have tried about everything, from running a gutted thermostat, to running no thermostat, even added an electric fan, and the super expensive super-cool anti freeze. Pump, radiator, hoses are all new, and engine was recently rebuilt. ( well about four years ago, but it only gets about 1K p/yr ) Dam thing has run hot since it was dropped in. not a problem in the winter, ( 185-190 ) but once the weather gets over 70 degrees, it runs 220, and gets there fast. I am convinced the three-core radiator just ain't gonna get it. ( and also, I recently threw a belt and the belt pushed a blade into the radiator, and it is toast )

LONG STORY SHORT... Who makes a four-core radiator whch will fit my 64 C10 with little or no modifications, and will COOL a 350 in 90 degree Georgia summers?

Thanks
