I've got a '46 Chevy 2-ton with a '53 235 in it. I have to replace the head gasket and while I'm at it, I figure I should put in a thermostat since there isn't one in there now. The question is what temperature should I put in? 160? 180? What did they use originally? I have a new aluminum radiator and it seldom get up to 180 even with a heavy load.
