Yeah so many posts and no solution. I am happy that there are responses. Doing a lot of the ole "let me check that again jic" which is fine. About the temperatures. The original guage spiked, replaced it with a SW guage it went up to 300 degrees with a 50/50 mix of antifreeze. Now for a dumb question (getting good at these).

What if the temp is the metal of the block and not the coolant? This is taken at the very back of an inline 8. Am I supposed to teflon tape the sensor insulating it from the block ?

The UV temp guage confirms the reading on the guage. This too is the metal temp. The UV temps don't change much front to back of the engine which makes sense since the metal will be fairly consistant across the block.

Guess it won't hurt if I did put a few dozen rounds of tape on the sensor. Would really suck if something so simple actually worked wouldn't it ?

All I can see on the Balancer is a yellow line no markings otherwise which is why I ask about timing marks. Good idea with the measurements.

Yes there is very little if any flow in idle when hot.
I see the water pulse when the thermostat opens but it really doesn't move until you rev it up.

Pretty much eliminated the items you listed plus many others.
