OMG!!! :whiney : About ready to lose my s***..... AGGGHHHHH. Flex fan in, 1/2" from radiator, high flow milodon pump, high flow water pump housing, high flow 160* thermostat. Still runs hot!!! idle, road, highway.... sits at 210* I DO NOT YET HAVE A shroud, but id think at speed the airflow would make up for it? WHAT THE HECK!?!?!?!?!?!?!?!?!??!!?!?

What has changed in your combo from this point in time??? It was exchanging heat and dropping the coolant temps.
"At idle in my carport it comes to 170* the t stat opens and it drops to 150*ish. when it warms that water up the stat opens again and hot water from the rad coms in and a few seconds later at about 210* the fan comes on and brings everything back down to 170-180* idling fan goes off and then on and so on. it works in the carport. This still happens. except now it has a mechanical fan. no electric fan, so it starts heats up, opens the t stat- comes down then slowly rises to 210ish. I took it for a test drive, it hung out around 200*-210* driving. seemed fine there, when i came to a stop it would slowly come down to 190-180* start driving again and it would go back to 200-210*. Maybe it isn't the best radiator? maybe the small ports on the housing don't flow enough water? maybe its a combination of it all."
now it heats up, and seems to stay around 210*, like its getting heat soaked. i don't know

It's pretty funny really. These overheating threads come up at least once a year (probably the same on other auto-related forums) and almost always follow this same course. Lots of suggestions, cooling system parts swapping, testing, all with little or no success. Sometimes people install massively overkill cooling systems and are okay afterward but how many people are out there doing just fine with the stock factory cooling system? Lots. I think the problem is that people assume the problem is the cooling system when the true culprit is elsewhere. There a LOT of lurkers watching but not participating because they've done it before, perhaps several times. OMG!!! :whiney : About ready to lose my s***..... AGGGHHHHH.

Had the issure yrs ago. Get a test kit to check for exhaust in cooling system. You never know. starter relay just died, have to wait till tomorrow. i will test head gaskets then. this is just a lil' 383, what does everyone else do for cooling? what rad? what pump? what housing? what if any shroud.

You ever get the stumble out of the carb?
Maybe try locking the timing out at 36 degrees? Without a start delay will be hard to start hot but a easy test to see if anything is different. NO, I don't think it is a timing thing. It does it under 1500 rpms. Maybe even closer to 1k. In drive if i give it any gas off idle it will pop through the carb and sometimes die. If i barely move the throttle and get the rpms going up then it drives normal.

Its lean.. the spark is chasing the fuel.. have you done anything to the carb.. you might try opening the mixture screws a 1/8 of a turn

I went to my buddys shop, he has also been giving me ideas. He lent me his blue point thermo gun. My in car gauge says 250* , The laser dot from the gun on temp probe says 180* I bring it back and he lends me his "expensive" thermo gun to verify. It reads within a few degrees of the blue point. I check over the whole motor, all exhaust several points on each head, the block, the oil pan the radiator etc... This means I have had 3 bad gauges, WHO THE HELL HAS THIS KIND OF LUCK???????? Also my exhaust at idle is between 650* and 850* the outer cylinders are 650* the 4 inner ones are 850*. I hate this thing right now!
