From one of my other threads, located at

I can almost guarentee that I can get as good or better mileage from a small block V8 and auto transmission geared for highway usage than the average Joe can get from the 6 and stick. The 6 has to work too hard. Just my 2 cents worth but based on 50 years experience."
What do you guys think? My assumption was a 6-cylinder stick would be the best for gas mileage, but I know nothing about vehicles, especially vintage ones.
What combination of engine, transmission, and other factors would result in the most efficient truck?
