Yes all stock AC/Heater. Gen1 SBC had an internal bypass in the head. I've also turned the heater on to see if it made a difference. As far as I can tell the engine temp is not really changing much per the thermal gun. As soon as I started seeing a change in the gauge reading by just cycling the ignition switch I realize it's not a cooling problem its a gauge problem.
