Having a high efficiency radiator isn't the problem. If the truck is running too cool, you should look to a faulty thermostat. If you live in really cold climates and never tow, yeah, I could see where the radiator would freeze up. Even big diesel rigs will block their grille from airflow in blizzards, but that's not the case here, is it? The lower mileage is due to the truck not getting out of the warm-up stage because it doesn't ever reach operating temp. Again, look at the thermostat. As for torque converters, doing the math is good, but on paper and real world are two different things. 2,000 rpm stall is a good minimum for these rigs. Even 2200-2400, especially if you're doing other mods. The higher stall will help the truck at around town speeds, actually improving mileage modestly since the engine is able to spool up into the powerband more easily. Agreed on aluminum driveshafts. Those things are really more for racing, not typical street (especially truck) use.
