My struggle with my 1975 Atomic 4 engine continues. Ive now moved on to the cooling system. We idle at about 150 ish and the tempature starts to increase with load. at 2000 rpm it hits around 200 degrees and icreases with load. While trying to pinpoint the issue I went to test the thermostat and realized the previous owner must have taken it out and the engine has no thermostat. I ordered a new Thermostat and a new tempature sending Unit and matched stuart werner gauge from Moyer. In The meantime I acid Flushed the system , Bucket tested my flow rate, Flushed my heat exchanger and tested flow and refilled, replaced my impeller. Nothing helped. Where Else should I look? Any advice??
