To Stat or Not To Stat? That is the question.

Now you should give us your conclusion.
What can we learn from your results?.
I have my view, but you made the effort and spent your money. What have you deduced from your tests?

Standard 4# radiator cap.

Read the end of my report. Conclusion is: There are very important reasons to run thermostats and no reasons not to if you use a high flow stat that approaches the flow Ford's original had.

Henry, I support your conclusions.

Very interesting that she was hotter without the stats while climbing, than with them.
What does that tell us about flow?

I'm not so sure it tells as much about flow as it does about the day I climbed without the stats it was 6° hotter than today when I climbed with the stats. That may have made a difference. I don't know.

What was remarkable to me was that even though the engine was about 5-6 degrees hotter climbing without the stats it actually leveled off at the same temperature that it did with the stats.

Henry, That's because the stats don't do the cooling, That is down to the transfer of heat energy from the block to the air, the rate of transfer, being the governing factor.
