The truck is a 1950 3100. Someone just narrowed my engine down to a 1960 235 from a Chevy car. I have no idea about the radiator cap. I have had the truck in the garage for just over a week and have not received my shop manual yet.
But I think the whole engine is coming out soon for a clean-up and revival. Maybe someday it will run again to see if this coffe can actually does anything.
