It's a dry heat

I'll throw this in here; When I built my first stroker, it would heat up around town, did good on the road, but got warm at slow speeds and them would boil over from heat soak when I parked it. Annoying and embarrassing. After a lot of experimenting, I pulled a fan from (I think) an 80s Dodge pick-up. It is huge. The blades are big and have a lot of pitch to them. The problem was, of course, that it wouldn't fit in the Cuda's shroud. It would fit the clutch just fine, but was too big to go into the shroud.
Fortunately, the blades are aluminum. I just marked them, cut them down to size and installed it. That did it. It moves an enormous amount of air. I had it on that engine for several years and have now had it on this Hemi for 4 or 5 years. But it will wear out a clutch every few years, depending on the amount of driving time it gets.
The fan may not be perfectly round or in balance. But it has not given me any problems and I spin the Hemi to 7,000.
Just one experience. Thanks for the note. Thats the way Im headed I think. Move more air . Although I would prefer a direct drive non clutch fan

Just to confirm , changing to a smaller diam upper pulley with no change to the lower speeds the fan up correct ? Correct. And speeds up the water pump too of course.

Ok,
I had nothing to loose so I wanted to try something .
So,,,, I put it back together with what I have. I gutted the original 160 thermostat. so now its nothing but a restrictor plate. I also bumped timing back up to 19 degrees base. Refilled it straight distilled water , added maybe a cup more of the cooling system additive. As the bottle says treats up to 12 quarts. this one was closer to 15 qts. Took it for a 25 mile test drive. So far so good. Its stayed well below half way on the gauge. Which by my earlier test , halfway is right at 190
Ambient temps during said ride were low 80s temps
Im going to drive it several times in a couple different environments before doing anything else to it
And as soon as I find a place its hidden , I will be adding a aftermkt gauge just for good measure before going any deeper.

Do you have a spring in the lower radiator hose? yes, added one while I had it apart the other day . Before I did this last test

Good progress!
Now on to reducing pinging to where you do not need to use a special gasoline blend?
You still might want a higher flow fan. I am planning a different fan , maybe. I want to drive it a bit and make sure all is good. before doing anything else cooling system wise . As far as reducing the race gas mix thing. THAT'S gonna require a complete tear down and new pistons. Thats a project for a day down the road a ways. Its not an everyday driver so $100 fuel tank fill ups dont really bother me to much .

UPDATE,
worked on it today
I bought and Installed a mechanical gauge today. So far , so good.
I also put an overflow bottle on it so it doesnt mark its spot anymore As the rad cap is a newer model designed for a return system .
Got it all warmed up sitting at high idle ,,,,, and the stock dash gauge needle pointing straight up the mech gauge is showing right at 170ish . Im gonna run it a while and see where it operates regularly . Im really starting to think im chasing a bad gauge or sending unit.
Got any updates?  Ive had it out a couple times . So far the car runs SUPER cool. Like below 150 degrees to cold cool with the gutted thermostat . IMO to cold . Keeping in mind ambient temps have been a tad chily around here I have a couple different temp range Stewart Components high flow thermostats coming and plan to replace both radiator hoses while its apart this time.

If it runs cold without a thermostat then your cooling system should be fine. Sounds like your old thermostat wasn't working properly. I had the same issue with an issue. The thermostat checked out okay when tested in hot water on the stove, but it made the engine overheat. It was a new thermostat but it didn't work properly. The next new one solved the problem. Lots of junk for sale at the auto parts store these days. My thoughts exactly New Stat should be here today or tomorrow

Thanks,
I used Rislone water treatment ( couldn't get Water wetter locally ) and So far so good.
with a gutted thermostat in it the car runs in the 130-140 range running down the road ,,,which is obviously to cold ( including expressway ) , It gets to maybe 160 ish range at extended idle
while you have the gutted thermostat in and the weather is cool, it might be a good time to do some experiments on pinging versus coolant temperature. Years ago (about 1999) I decided to do an Oxalic Acid flush of the cooling system of the Magnum 5.9V8 in a 1995 Ram. With distilled water, Prestone Oxalic Acid flush and no thermostat I pretty quickly noticed that the light pinging on 85 AKI gasoline I usually had in the hot 95-99 North Carolina summer weather disappeared. My coolant gauge and scanner readings showed 145 degrees coolant temperature. I tested for pinging on a steep 4% grade hill by going to full throttle in 2nd gear. My fuzzy memory is that a 10 degree coolant temperature change leads to 5 Octane number fuel requirement change.

One step closer.
Stant superstat on the left.
Stewart industries high flow on the right.
It with new radiator hoses go on this week.
Time will tell soon enough if im on the right track Bill do you mind relaying what degree thermostat you installed?
