My temp guage has never read right (i think) on a 88* day in south fla. it doesn't go over 140*. I have an electric fan (hayden 24339) don't know the cfm rating but it blows like hell. no heater core. the motor is a 383 with edlebrock e-tec vortec aluminum heads. the sender is in the head between # 6 & 8 plugs. should it be somewhere else? i mean temp is temp, right?
