Re: 1969 396 Radiator overflow leak
I "overfilled" my 69 BB radiator once and it spewed a couple times after shutting it off then it found its happy place and stopped. It was around 4" below full. You need to make sure the car is not overheating. Do you have a temp gauge? Does it run hot while you are cruising or sitting at idle for a length of time like being stopped at red lights or traffic? Point is, just make sure its not overheating. If its good, it should find its happy place right about where yours is at. If it continues to spew even lower, you need to determine the issue.
