Sounds like you have done all the obvious to try and solve this problem. Now your going to have to dig deep. First what is the history of the engine, is it a fresh rebuild, what is the bore size, or is it a 40 yr. old engine. Any white smoke when you first start the engine out the tailpipes? If so I would pull the plugs and look for any sign of coolant on the plugs, they will be white if anti-freeze is leaking into the cyl. Another concern is a possible leaky head gasket, or a cracked head. With unleaded fuel it is important to have hardened valve seats, many of the old heads have not be upgraded to these seats and they will leak around the exhaust seats, leaking coolant into the cylinders. If the head gaskets have been replaced lately, were they installed correctly? If you do take the heads off have them magnufluxed and checked for cracks. What about the waterpump, is it working properly? When you sort this problem out you will have to reinstall the thermostat, it is important to restrict the flow with a stat for proper cooling.

O.K. so you have tried two rads, were they new, how many rows did they have? 440's run hot, so your gonna need all the rad you can get, my buddies 440 won't live without a 4 core rad. I know another that has an aluminum 29" cross flow before he could drive his car anywhere. So since it looks like you have a solid motor I would be looking at putting in the biggest and max. flow rad you can find, with the biggest clutch fan you can install. An auxil.push fan is also a good idea mounted on the front side of the rad. Good Luck

Thanks for info,one radiator was a glen ray 22" 3 row high efficiency, the current one is a wizard cooling 22" 2 1" row high efficiency with 4 8" electric fans on a 185 sensor.This car gets so hot you can still smell the engine paint burning and it has 2000+ miles.It actually got hot enough to melt the steering column bushing.

Wow, that is defenitly two hot, even if you have to do some cutting go for the 29" cross flow, sounds like your gonna need all the rad you can get. The cross flow design is superior to the reg. 22" mopar rad, I run a 26" aluminum in my street strip car and I actually had to put a 185 degree stat in it to get the engine some heat. With my 22" 3 core I couldn't keep the car under 200 degrees.

Running a car without a stat is a bandage approach to solving a problem, what do you do on a cool night, run it at 140 degrees operating temp.? Hot 68bee, if this is an original car and you want to retain the stock appearance I would suggest you take one of your 22" rads and having it recored with what they call a K core, have the shop install 4 rows if possible, this worked for my friends 440 and it is liveable on all but the hottest of days. The K core increases the cooling capacity by about 25%. Good Luck

Just wondering could you be running Lean? Too much timing? A fresh motor will make a lil more heat while breaking in[especially a tight one], is it auto or std? When it comes to belt driven fans use the flex o lite 18'-19' fans. Don't bother with factory boat anchor 7 blades nowadays there is better stuff out there and for less money.

Ok I do realize it's a bandage approach, But it does work, its cheap,easy, and for me there are no nights cool enough that it would run anywhere near 140 degrees. It actually runs at about its normal temp. I would much rather have it run on the cool side than experience damage from too hot.

Yea while neither is a good thing, I'm with you. It's just a lil easier on the nerves.
