UNfortunately,this is the one area where ford came up short in designing the FE series engines.All 352-428 built from 1958-1976 are prone to this kind of tantrum since they didnt design the cooling system well enough to handel all that cast iron.In your case and mine (62 390 in a boid) 600 pounds worth of cast iron.The intake seems to weigh 100 lbs by itself.In trying to solve your problem,flush all the coolant passages including removing the block drain if possible.make sure the thermostat is opening and closing properly.check to see if the fan clutch is working and that you have a fan shroud to help channel the air through the radiator properly.Also,check your timing to see if it is accurate,if its to high,that will cause overheating and a blown head gasket.Look to possibly upgrade your fan to a flex-a-light fan,a four row radiator(aluminium if possible) edlebrock or wieand water pump(they reportedly out do stock by 100%) and also a high volume oil pump as well.I hope this has shed some light on your situation.As a relative new comer to tinkering with old fords and submiting post here,i too am getting some great tips on how to keep FE engines happy. |
