I got a 1970 Nova with a 383 stroker and a Turbo 350 trans. Its overheats under a load after about 30 mins. I installed an all aluminum, 2 row radiator and a 180° thermostat. The radiator is solely for coolant: I have a separate cooler for the trans. I also have an electric and flex fan on it. There is no heater hoses/heater core attached to the cooling system. The car runs great but this overheating issue is driving me crazy. The only thing I can think to do is replace the water pump with a high flow all-aluminum one. Help please!
have the same problem?
