Needing a little help with my 59 Fairlane new water pump new 4 row high efficiency rad. Still wants to climb and peak doesn't boil over just pegs the gage. when I shoot it with a heat gun my temps seem to be the same both going  in and coming out the rad.( 195') core temp is around the same.  Pretty sure I need to turn the pump a little faster. Soon as I speed up more RPM little more air the temp comes back down.  Dose anyone know off hand what smaller pulley I could use and specifically what year and model would fit.  Thanks Dave  406-698-0489
