    If you have the stock distriutor and running a four barrel carburetor your ignition timing will not be right no matter where you hook your vac*** advance to on the carburetor or intake. I would contact GMC Buba for one of his converted chevy distriutors. Without proper timing your power with be down and heating will be up.

    Flathead Ford V8s have exhaust p***ages that go through the coolant, and therefore put more heat into the cooling system. However it was designed for this and does no harm, as long as the cooling system is in top shape.

    If your cooling system is working well now, but you want extra protection in traffic on hot days, you could add an electric pusher fan along with your stock engine fan. German luxury cars are set up this way, have seen both fans on Mercedes, BMW and Audi.

    Chev and Pontiac minivans have a good pusher fan. Most cars these days have a puller (won't work in front of the rad).

    Of course this ***umes you have 12 volt system.

    You could hook it up stock style with a thermostat or just put a switch on the dash and watch the heat gauge. In any case, you will need to use a relay. Cooling fans draw a lot of power.
     
  4. Haha Im with you HR...I have two FHs. The blown one runs 95% of the time WITHOUT the fan on and the other 21 stud FH barely registers temp on the mech gauge - I mean it struggles to get to 140 after idling for 45 mins, which means its running too cold.

    Any internal combustion engine engine will overheat if the operating parameters are not engineered to work together ie: timing, fuel/jetting, compression, rad capacity, cap, coolant type etc....thats whay they call it a cooling SYSTEM.

    The parts have to work together to cool the BTUs that YOUR engine combo produces. Remember fellas, our cars are not factory engineered - you've moved the goal posts by changing the above parameters.

    So imo the sbc ****ogy is simply ignorant at best.

    If you burn your finger, do you want a trickle of cool water on it, or the whole faucet flowing over it?

    If it stays in the radiator longer, it stays in the block longer and gets hotter - there is no free lunch.

    What do you mean "not staying in the radiator long enough"? I don't know about your car, but in my car, there's is always coolant in the radiator.
