Zerostart 8000 Series Tank/Circulation Style Engine Heater
I just picked up a Zerostart 8000 Series Tank/Circulation style Engine Heater... I do not have a different winter car so I am stuck driving the firebird, for a while my car hasnt been warming up for a while so I picked up this heater. The directions suck and say that the inlet location is from the engine block drain hole, the haynes manual says the only 1 is from the radiator.
anyone got any ideas how to install this pump heater on the 305 TBI?

There is a water jacket drain plug on both sides of the block. The one on the passenger side is occupied by the knock sensor, so you're going to have to use the one on the driver side.
