I’m having the same problem. Have 1row Griffin radiator, this is the biggest I can put in. Have March pulley system plus Magnum Force coilover , rack and pinion K member. Support pipes on the side power steering pulley close to fan. Have high volume water pump, high flow thermostat. Did ok in cool weather but live in south Texas. Have even put that stuff that is supposed to cool down 20 -30 degrees. Looking into another radiator. Run two radiators. Going to go to the Martin Bros. Shop and ask them about what I can do. Some people are saying it’s ok to run 195 - 210 , I don’t like that high
