I will elaborate.

You state that carburetor icing will not happen and that I know it. Most interesting that you can tell what I know from miles away.

"Nobody is taking their Packard out to get the family Christmas tree.." you state. "Even if I took it out in the snow.. the underhood temperature.. would keep the carb and pump ...warm." Warm pumps have nothing to do with carb icing.

These statements indicate that you do not understand carburetor icing. I referenced various onloine sources to refresh my thoughts, suggest you google carburetor icing.
It is most common above 32 degrees and can occur up to 75 degrees, moist air is the culprit. When air goes through the carb venturi it cools markedly due to the "venturi effect", the moisture in the damp air condenses and freezes, sometimes closing off the venturi completely. It is a current problem mostly in small piston aircraft but used to be more prevalent in cars before Packard invented the Fuelizer in about 1920. The ideal temperature of an intake manifold used to be 120 degrees, not sure what it is now

I knew this before adn I know it even better now, despite what your beliefs about my knowledge may be.

Your "theory" that you cna't do enough to keep a motor cool to make it last longer is contrary to 100+ years of internal combustion engine research and practice. In short,. it's wrong. New cars have higher temp thermostats and high pressure radiator caps, look at a temp gauge on many new cars whose engines last 200,000 miles any you will see the midpoint number on the gauge is often over 225 degrees.

Why do you think cars have had thermostats to keep the temp UP to 160/180/195 degrees?? Without them they would 140 or so. That's because they run more efficiently (MPG) at higher temps and contaminants including water are "boiled out" of the crankcase oil.

There are many many other incorrect assumptions/facts/conclusions in your last post, suggest you read some books on theory and design. You ask for ideas and help, then you call me a liar?? I know what I am talking about and if I'm wrong I admit it in the forums and correct it. Because that's the way it should be done.
