Op said it did it with AND without the shroud..I would still like to see a better picture of the shroud
I am assuming he means overheated at speed and at idle.

Have you VERIFIED the engine is really over heating? Do you have an infrared temp gun? 20 bucks, so get one if you don't. That can tell the story quickly.Yeah I was thinking that also so I disconnected the procharger and charge tube and it still does it. Mind boggling!
Ok. Good enough!It's a 1/4 inch away from the frame rails on both sides!
I saw where you said that once. I still want to see it.Op said it did it with AND without the shroud..

It also runs hot on the road. I mentioned the fan once already, but that's only at idle.I stopped at post #1 & read no further. A 'toy' fan, 2250 cfm?
Large factory flex fans pulled in excess of 6000 cfm. Not hard to see where the problem is.....
That might explain the idle overheating but not the at speed over heating where the fan does not have an effect.I stopped at post #1 & read no further. A 'toy' fan, 2250 cfm?

This statment by the OP points directly points at a coolant flow issue.It got better when I gutted the thermostat. Sending unit is at the waterpump housing.
Interesting observation. I believe "somewhere" in all this he said it was a high flow water pump, but that's null and void if the impeller spins on the shaft. I've seen it too.This statment by the OP points directly points at a coolant flow issue.
Which water pump are you using?
I had this same problem with my BBM stroker, over heated all the time.
I found that the impeller was spinning on the drive shaft in the water pump, cut down the coolant flow a lot. After posting about it I found that is not an uncommon issue.
That is not a good location for the coolant temp sending unit, that location is before the coolant passes through the engine, this would actually read cold. You want to read the coolant temp at the hottest point, the cylinder head or intake manifold at the T stat, this you give you a true coolant temp reading in the engine.It got better when I gutted the thermostat. Sending unit is at the waterpump housing.
It doesn't have to be. As long as most of the core is exposed, it's good, since the water is moving through the radiator, it will see air flow.Is the front of the radiator support open to the entire radiator core?
Rusty in my case it was a brand new Milodon high flow pump.Interesting observation. I believe "somewhere" in all this he said it was a high flow water pump, but that's null and void if the impeller spins on the shaft. I've seen it too.
Like the old saying goes, new don't mean good. lolRusty in my case it was a brand new Milodon high flow pump.
My $150 cheap summit one is... Never a problem...It's a 1/4 inch away from the frame rails on both sides!
YesIs the front of the radiator support open to the entire radiator core?
Great idea! ThanksSomething to try as an experiment. place a high cfm fan like a furnace blower/ carpet blower or multiple fans directed ar the front of the radiator. See if this changes the overheat at idle condition. Try with and without shroud possibly. This might help narrow things down based on how it reacts. It's also easy and inexpensive if you have or can borrow the fans/ blowers.
No had a different radiator which I put a pusher and puller. I have no clearance to put bigger fans or bigger shroud. Matter of fact in order to get a shroud at all I got this radiator which the motor is inbedded in the core itself! Expensive radiator!That shroud is blockin a LOT of real estate. Running without it makes no difference at all?
Yes it will shut down! And I have a thermal meter!Have you VERIFIED the engine is really over heating? Do you have an infrared temp gun? 20 bucks, so get one if you don't. That can tell the story quickly.
