Blew rear freeze plug on 408

I took my Swinger for a quick drive yesterday and got on it for the first time since building the car .
It hit 7k pretty quick then I could smell coolant . Luckily I was 1/4 mile from home . I popped a heater hose off on an earlier test drive but attributed that to the idiot that assembled the car not tightening the hose clamp ... LOL
Either the freeze plug wasnt seated tightly or I have a head gasket problem .
