Ford

I have a 1973 ford f100 it has a 302sb i bought it a few days ago and drove it home and it started to run hot so i put a new water pump and thermostat and it still runs very hot and water it spiting out of the right side of the exhaust can someone help me! ! ! ! ! ! ! ! !

Is there white smoke coming out of the exhaust? if there is a lot of white smoke, it sounds like the head gasket is blown or worse yet the head is cracked.if there is no smoke it is possible that the radiator is plugged and need to be "rodded" out.
