I'd be tempted to toss on a cheap fixed blade fan just for testing purposes.
If you really read up on the Evans coolant you will learn it doesn’t transfer heat near as well as Water. Obviously you will need to have something for corrosion purposes hence we normally run a 50/50 mix of ethyl glycol and water as the glycol doesn’t transfer heat as well as water either. Since it doesn’t transfer heat as well you will need a cooling system that is more than up to the task than you would normally need with a water based liquid.
When I first installed my 408, I was having some doubts about the Evans Coolant I was running with as temps were in the 210* - 220* range. I made some other improvements to the cooling system - the shroud making the biggest difference and I have no cooling concerns whatsoever - pretty steady at 187*.
Lots of good suggestions above - in my experience, it's not the coolant.

I have used these fans for 3 cars now and they are the best I have found, I used a flow meter and checked many different fans and the 3000 cfm advertised fans never pushed more than 1500 cfm. They told me there fans will push 2500 cfm or more and It measured at 2470 cfm.

Unless I’m just horrible at searching for standard fans I can’t find a clutch fan that will fit my set up.
If I had the room you do I wouldn’t have a problem running a clutch fan. But a 440 with a 4 core radiator means I have 2” of clearance between the rad and the water pump.
3000 aint enough to cool a big stroker to start with !!
In my book those temps are to high.Just got back from taking the car out for the first time. Got hot in the neighborhood 230, and cooled down to 200-205 after a mile or so on the highway at 50-55. BUT when I got home I discovered that my number 7 plug wire was pulled out from the sparkplug. Looks like the steering shaft caught the boot guards I had put on and ripped the wire off I'm assuming right at the start of the test run. I thought something sounded off but given this was the first time I had driven the car I still don't know all the different sounds and noises its going to make. Once this rain stops I'll take it back out hopefully on all 8 cylinders this time.
In my book those temps are to high.
What was the ambient temp?
Plug wire wont make a bid difference.
Well like stated on your thread before your cooling system is too small.Agree on temps being to high hence the thread .
50s with cold ran going over the rad. So pretty much best case and it didn't cool down to the 180 thermostat temp
Well like stated on your thread before your cooling system is too small.
If it will not cool down to the thermostat while driving down the highway - your radiator does not have a enough cooling capacity.
If it cools going down the highway but gets hot when you slow down or at idle - your fan is not moving enough air.
Contact the folks at Griffin.
This will not be $cheap.

One last thing.Yeah as much as I'm not liking the idea of spending like a grand on a new rad its looking like I'll have too.... I'll look at griffin, have talked to US Radiators as well.
There are plenty of options that won't end up costing a grand. As mentioned - look at what AndyF runs for a cooling system.
Griffin "Exact fit" radiators.First of all I want to thank "512Stroker" for sharing your experience . I learned a lot . I am experiencing the same issues with my 383 scamp . After 5 minutes of running the temps go to 220-230 . these engines were never intended to operate at these temps and I don't want to cook my motor . I am thinking that my oem radiator doesn't have enough volume to cool properly . so I went on a search . Every vendor wants to sell you a radiator but won't give out the overall dimentions . Or don't know what they are or …. I am of the opinion that (2) 1 1/4 or (2) 1 1/2" cores will do the trick . The question of bolting it in is the big issue . I'M not hacking up my finished car just to get a rad to fit . Again , thanks 512Stroker
