Hey, i'm new here and thought i'd post a question and see what you guys thought. I have a 1969 Camaro RS and i was driving it and then the upper radiator hose blew and split the radiator open. Well anyway, we got a new hose and radiator and started filling the radiator up with antifreeze and water. Well we got about 5 gallons of water and antifreeze and then it starts coming out the tail pipe. And my father said it's either a warped head, blown head gasket or a cracked block which i don't think its a cracked block. But what my question is, if it filled up with that much liquid and stuff what do you think it would be, a warped head, blown head gasket or a cracked block?
