I have a 1943 Chevy with 216. It crankes right up and purrs like a kitten. It starts to run hot in about 10 mins or so @ a idle. I thought it was a water pump problem so I just replaced it but that wasnt a fix. You can take the cap off the radiator and the water doesnt move much unless you rev the truck up bit and then is sucs down and will come back when you let off. The oil is good with no signs of water. I pulled all 6 spark plugs and they are all dry. I thinking maybe something with the head or head gasket but dont know much about that. Anything suggestions on what to try first before I pull the head? Thanks for any help
