I have never seen anything but a 180º in any truck that i have dealt with. Because of the huge frontal opening have never seen one get hot when rolling, but they will get hot sitting still idling both in and out of traffic.
Yall get to mixing too many none truck issues in this forum. IMHO

Mine was in a truck and I'm speaking from Truck experience myself. Stop and go was not a good deal for me and a 180 stat. Also I wasn't running a stock 428. I guess I should have wrote that in but most people know me LOL. JMHO
I've heard tell, 190*+ thermostats are good for gas mileage. :)
I know my gas mileage goes down with cooler temperatures.
On my last trip for the latest example of that. :/
And the gas mileage went to -hell- when I experimented with a 160*
thermostat back in the late 70's.
But uh... what brand of transmission you got there, Wes? :)
Oh crap... :/
Don't tell me its an automatic. :/
If it's an automatic just pretend I didn't say nuthin', ok? ;)

Wes, I don't see anything that would restrict air flow and require additional cooling. Am I missing something?
Bear has a nice looking truck in his sig though, don't you think?

I ran a NP 435 without any trouble. Some people thought I had an auto in it! I found a good secret on shifting those without any problems and very quick shift!
Wes, I credit you for knowing a lot more about engine building than me, but your last statement left me dangling.
Why would boring your engine 30 be any different than mine bored over 30. Timing and fuel load can raise the operating temp but a 30 over bore shouldn't. IMHO
You really have me confused with your cutting on comment. You will not get far from the driveway with your thermostat closed. That circulating thang must occur.
I've read all of these treads and have learned a few options. But, one thing Ive noticed with messing with and trying all those different ideas, is that it was the radiator from the beginning. Tin stated he flushed it but went no futher as some requested to have the tanks removed. I'm not a super mechanic, but when a flex fan is used and your high reving sitting in a mud hole without airflow and max waterflow? = HEAT.. I'm glad you finally changed the radiator. NICE truck Bear!!

Yes! :)
Without the radiator being up to the job, none of the other stuff is going
to do squat.
I had a new 4 core radiator, new 12 fin F.K water pump, R.S thermostat and
-still- showing signs of trying to get hot sitting in traffic (with the A/C off).
The final piece for me happened to be the "idle" ignition timing. :)
Learned that right here. :)
Trying to piece meal a cooling system problem and expecting it to work
"like new" is like expecting to be exempt from the laws of the universe.

My 428 has thin walled cylinders!!! I dont think you quite understand cooling. Lets say that you are running a 160 Stat. After running a while, It starts going past 160 to 170 and on up! What is happening is your HOT water that's going to the Radiator isn't getting enough cooling time before it recirculates. So then your stat is open all the time with no real cooling off period in the radiator.
So you drop in a 180 or a 190 stat. It never goes past that. That's because you are giving your HOT water time to cool off before the next cycle. Does that make sense???
Yes, timing and fuel do play a part of that as well. Sorry I didn't explain where I was coming from or why! I do see people make that mistake one to many times on to cool of a stat (160) and cant understand why it doesn't always work out on the street with an wormed up engine (or whatever your situation may be). And you wont cruz around town on that before you have to park it. JMHO
I forgot to say that the 180 on hot days (100+deg) driving in stop and go traffic. Started to creep up to 200 or so. I dropped in a 190 and that helped a ton. Just because it gave it a little more cooling time in the radiator!

Too secret to share? ;)
Shift it like a truck? (no clutching)
"I ran a NP 435" ...so what are you running now?
--------------------------
Could thin cylinder walls transfer heat into the water that would otherwise
go out the exhaust pipe adding to the burden the cooling system is under?
But why the difference between thermostat opening temperatures?
Could it be that his thermostats were of different types?
Robert Shaw type compared to the more restrictive? ...or something?
