Reply to "Advice post engine build, engine runs hot at idle"

Today I decided to start her from cold just to see how long she would take to hit 230. Started the car and for the first few minutes she sat around 2500 at fast idle. Finally she lands a hair below 1100 on idle. Took her just over 15 minutes of sitting in the (conditioned/75 degree) garage to slowly and consistently creep up to 230 at which point I cut it.

I don’t believe it to be air in the system as the temp very slowly and consistently rises, there is no up and down.

Also of note she does not run on. She cuts immediately when I turn her off. Both fans were very forcefully pulling extremely hot air from the Fluidyne radiator.
