I have a '51 3100 w/'58 235, Offy 2 carb and Fenton headers. I installed the LMC electric fan in front of my radiator and do not have a fan on the water pump. For the past 3 days, the temperature here has been mid to high 90s. I have been driving the truck around town pulling a 700 pound Teardrop Trailer and the temp has not gotten above 185 degrees. For those that are wanting to use the fan...I highly recommend it.
