Hey guys.
I want to double check my temp gauge and thermo stat in my 59 with a 235.

It was about 68 degrees last night and I ran the engine for about 5 or 10 minutes and the gauge only went up just slightly past the first line. I was sitting in the driveway

How hot should a 235 run at running temp?

And where should I check it at? On the Head? I will be using a infrared or maybe a thermo couple temp probe. I have access to surface probes, infrared probes and liquid thermocouples I can even get a big mercury type thermometer. Thanks to my Job
