Yes, heat blows out of the vents, to me that equals more displacemt of heat and cooler temps. I’m having the opposite affect. Electrical problem?

Once again; If it doesn't STAY above 220F you have "normal" operation. You displacement of heat theory is a marginal difference, at best. The temp control knob should have no perceptible affect on engine temp.
If you are turning the defrost on or putting it on recirc mode the AC compressor runs with no indicator light.
Presumably the new engine has a new water pump and t-stat?
For Cat Man: does hot air blow out the vents when the temp control is turned to hot? I was trying to save me finger tips, to no avail; ended up typig 5 times as many letters.

I appreciate all of the help, this is a pain in the AXX. It’s been in the low 70’s here and the car runs around 194° unless I turn the heater on, then it’s will go up 20° to 214° within a minute. I noticed the heater gage doesn’t seem to move. I’m wondering if the electric components could be affecting the digital gage? Has anyone heard of anything like this?

The temp sensor/gauge is desensitized near the normal position so people don't see it moving all over the place when the stat cycles.

Why agonize over NORMAL? ?Never even look at the analog gauge.

As I have mentioned, sometimes when I turn the heater on the temp does not move. I can drive with the heat selector to the right in the red until I turn the car off and the temp stays the same or only moves a degree or 2. On the other hand, sometimes more often than not, when the heat is selected to high the temp will shoot up from 194 to 221. I don’t think that is NORMAL under any circumstances. Only turning the heat selector shouldn’t have a difference I’m trying to figure out what is happening. Today I noticed the heater, did not blow hot air all of the time, it was intermittent. Does the mean that water is not flowing through the core, at all, not fast enough, is air in there (doesn’t make any strange noise).i have had this car for 70k and it’s hasnt behaved this way until recently.. It’s not normal.

OK, get an ulcer over it. As long as it doesn't stay over 220F it won't hurt anything. Swings between 180F-220F are normal.
If there is air in the core you will hear a gurgle sound from the waterfall. Maybe the core is clogged, but you have 2 other coolant detours; oil cooler and turbo.
The route the coolant takes in the core is from the engine back to the engine. It not really a part of the "cooling" it is on the "heating" side of the t-stat.
Maybe turning the fan on changes the resistance reading of the temp sensor? Is your battery and alternator getting ready to die? Are the grounds all good? Is there a disturbance on the low ref?
Maybe the sensor is bad. It is a diode type sensor; one side is low ref the other is signal. Maybe the connector is corroded?
While 194F is ok, it is a bit higher than expected. Maybe you are a victim of a bad parts guy that supplied a 190F t-stat instead of 180F. Does the fan ever turn off? ACDelco 131-158 is the only reliable t-stat, even the cheaper ACDelco Pro won't work right.
