So I put a new radiator in, Frostbite Aluminum Radiator 4-Row 67/69 V8 ,Fan/Shroud Package FB509H, to fit it, a new water pump,FlowKooler 1649 - Hi-Flow Mechanical Water Pumps, still heats up, I set my advance to 6*,still heats up, cannot even drive it, going down hill, still does not seem to cool down? this is a rebuilt 400, runs pump gas, no high compression engine, was running cooler with my old radiator, a brass 3 row?
