You might consider doing what I just did and order an aluminum rad. I just ordered my from street or track because they give you a bracket that moves the radiator in more so you can get a bigger electric fan but the wait is about 5 weeks. If you don't plan on useing a electric fan you can just order one from summit.
i run a flex fan attached to the engine, as well as a 12 inch electric fan in front of the radiator as well. i know the flex fan isnt the best at doin its job but it shouldnt make a 35+ degree difference

Try a 160 degree thermostat and the biggest clutch fan and shroud that you can fit in it. Get rid of the electric fan in the front because it could be blocking more needed airflow at idle.
for what it's worth .... I too was experiencing over-heating at stops on a fairly stock 289, Holley 4 bbl, 4-spd .... have 180 deg t-stat .... flushed the entire system .... for better or worse, I replaced the rad with a new 3 core Modine (from CJ Pony) *and* added a matching shroud .... I reused the original stock 4-blade fan too (yes, this may seem odd, but that's what it had when I bought it 1970, and *NO* shroud) .... got a new belt and tensioned it properly .... using pre-mixed permanent 50-50 coolant (contains demineralized water) .... new hoses all around while the system was apart .... old water pump still in service .... also added a new overflow tank (stainless steel unit from National Parts Depot - this tank looks really good mounted on driver's side of rad to front cowling) .... the new rad also has a wider core (1 1/2" on both sides) than the "original" rad .... still fit the mounting holes perfectly .... all of this has corrected my over-heating problems ..... the shroud really helps the fan pull air through the rad instead of sucking air in from the sides .... also, for proper cooling, heed the 50-50 mixture ratio of the coolant .... too much either way will cause poor performance of the coolant -- i.e., won't cool adequately .... Ford Muscle did a couple of articles, one on new rad (3 core) and another on electric fan from an early Taurus 3.6L .... I acknowledge an electric fan has advantages, so that mod will come when I get to doing some serious engine overhauling and an upgraded alternator (3G+) .... hope this helps ....

hahahah oh my robert....if i have to read another thread of you on cooling 
.....get rid of the flex fan and use a big block rigid 6 blade fan....i run everything you do, except with 2 differences....i dont have a fan shroud, and i use a big block 6 blade rigid fan and driving it in texas heat and humidity i never saw over 185

i dont have a fan shroud either. someone replaced my radiator with one not meant for the car. the had to cut into the battery tray to allow for more room.
so a 6 bladed fan? what if i got one and had it say powder coated or chromed?

Has it allways run hot?
Are you sure your air/fuel mixture is adjusted correctly?
Stock pulleys? or aftermarket?
have you replace your radiator cap letely?
A bad cap will not let the system build pressure=cooling system wont work well.
I would also get rid of the pusher fan, and get a good electric fan (puller)
if thats out of the question , a standard fan AND a shroud.

i have a 180 stat (my temp gauge must be 5 degrees off cause it says 175 when it opens)
i dont have a shroud either. i havent changed anything in a long while. im gonna go to my used stang parts guy and see if he has a big metal blade i guess. try it out for abuot a week. if it works it will stay on. if not its goin back

if it runs cool while driving it is most likley an air flow problem over the radiator. I know a fan shroud makes a big difference especially in 65-66s. I just upgraded and built a 5.0 and added AC so I am looking around for the perfect cooling solution for here in socal with my combo.
My old combo was a flex, fan 3 core stock radiator, and an electric pusher for the 91 freeway parking lot. On 100 plus days it rarely went over 210. I think the hotest it got was 215. When I installed the cheezzy Ford shroud the average temp dropped 10 degrees. from about 205 to 190.
