What size is the core? If it's the same size as a stock 26" fan, there's only one high performance solution. https://board.moparts.org/ubbthreads/show...part=1&vc=1

You should consider that if it's already "moving good air" that it's probably moving the air good enough, or maybe even more than enough. I'd look elsewhere to solve the problem. OR..... if it is NOT moving enough with an electric fan setup, I'd move away from electric fans and go thermal clutch fan with a shroud after I checked the timing

Radiator is 24x16 tanks on top / bottom Fans are 12" 1400 cfm each.

I will look into the benz you have but, I don't think I will have clearence to engine because it is a single fan, motor in middle and like I said I have a 3" think 4 core rad. May be tight fit.
Thanks-
Really!!! Benz fans!? Ok. You have not even checked the basic things yet.

How "hot" is it running and under what conditions?

Agreed. Thermal. Copper. Green coolant. 180 Superstat. Shroud.

I doubt that is your issue. Do you know what your initial timing is?
You are really hung up on the fans and thermostats! I can almost bet you are way off on your timing. That is a lot of motor for someone to make comments like "the timing is not advanced".
I PM'ed you with some questions. I think you will get a lot more information if you start with the basics.

Ok, here is some more detail:
It is new stroker 72 400 block 30 over to 499 stuffed in an A body 68 Dart. Built for street / strip.
Problem might be aggravated if the engine's not broken in yet?

Hi Flow mech water pump. Using water and the wet water additive that says it helps reduce temp.
There was a batch of aftermarket alum waterpump housings that reportedly had small passages in them. I don't know anything more than that nugget, you'll have to research that one.

Let her run at idel, took around 18 minutes before it climmed to 205 then I shut it down.
205° isn't quite dangerous at idle/no-load, it's just higher than we gearheads want. How much higher would it go? If it's 95° ambient, settling in at say, 208° at idle might be 'normal'.
Quote:
I took her for a ride and it stayed around 195 till I slow down or stop at a light then she quickly starts to rise and I am forced to shut her down again. I then put in a 160 thermostat and it did not help.
A 160 T-stat will not make an engine run cooler if there is something under-performing in the cooling system. It will simply make it take a little longer to get to that first T-stat opening point and maybe a few after that. Meaning - it buys you a little time, but doesn't change the equilibrium temperature of the system.

So I assumed I needed a stronger cfm fan.
what thermostate were you running during the part in yellow?
now that you put a 160 in it, what does it run when you are moving?
it sounds like an air flow issue, if it maintains temp at speed, but not at idle.
not saying there aren't other things to do to help bring temps down, but I don't think a timing change will solve it all either.

I started out with a 22x16 champinon 4 core rad along with a 16" Zirgo electric fan that stated it pushes 3000 cfm. It would not fit as a puller, so I mounted it in grill as pusher. I did have enough room for a mech fan with no shroud so I ran that as well. No thermostat.

A pusher fan .. mounted on the grille ? ... IMO ....
WHAT will it take to get a puller in there ?
