1970 Corvette running hot and boiling over

by Rob
(Palm Coast, Fl)

My 1970 corvette (350)is running hot by the water temp gauge. I parked it in my garage, shut it off, opened the hood and it was gurgling pretty good and then within a minute or so began piss out of the expansion tank hose and bubble out of the tank lid. The engine was completely rebuilt several years ago. About six months ago my heater core began leaking so instead of repairing it (I live in Fl and the car does not have AC and I don't need heat), I bypassed it. not sure if this could be a problem. I'm thinking possibly thermostat. Radiator is new.
