The difference from the freeway to sitting in traffic is air speed(fan) & water pump speed. Most likely to be air speed . What do you have for a shroud/fan. What water pump?

So you don't have a gauge on it to know what the ACTUAL temp is?
No, interior is 100% stock/factory. Never got an actual temp gauge, I guess that is where I should start. I wanted to keep it as factory appearing as possible but I figure its time to get a new aftermarket gauge.

No shrould, just aftermarket puller fan 3000 CFM i believe.
Unsure about the water pump.

So I take it you are using an electric puller fan? Move the puller to the front and use it as a pusher and put it on a thermostatically controlled switch. Then add in a stock type fixed fan to your motor and your problems will go away. A fixed fan flows a decent amount of air at idle, and with the help of a pusher the two should not have any problem cooling that motor.
Well I cant do that b/c I have the AC condenser and the tranny cooler in the front of the radiator.
Let me go snap a few pics for you guys---

edelbrock or milodon water pump. I think that elec fan is not moving enough air especially with all the hardware in front of the radiator.

with how it sits now-- what would you do? get a better fan setup? dual fans? move the condensor and tranny cooler?
Right now im looking at replacing the water pump and thermostat to a 160. Im also going to get the correct radiator cap Monday.

All this nonsense about "puller and pusher." There is ONLY ONE WAY that air should ever go through a CAR radiator, and that is from front (of the radiator) to back.
MAKE SURE the fan is the correct type and is turning the correct direction. You should be able to see this by looking at the fan blades. The will be "cupped" on one side, and this is the side that they should "pull" to (Blades are like wings--they are more efficient in one direction than the other) Some fans will change direction just by changing the wiring polarity, and they will NOT WORK WELL when reversed!!!!
I know nothing of the track record of the specific fan you have, it simply may not be enough

You know it'd sure be easier if a good aftermarket W/P took care of this as the W/P would be a much easier install. Also I'd get a high flow 180 stat( drill a 1/16" hole in it for easy fillup). 160 is way too cool ex for a drag racer(& you are way above 160 degrees). The A/C condenser & trans cooler have to stay. I do not have the last word on fan advice but the old standby of a properly spaced(into the shroud) thermal clutch fan would be what I would do. there's just not enough air going thru the rad fins. EDIT yes that is the correct pump though I would check milodon & see if their pump is cheaper.

Or a simple test would be have the car running at idle and take a piece of paper and put it on the front of the rad and the fan drawing air in through the rad should make the paper stick.
I have the exact same AFCO set up as you for my 340 challenger, i dont have the car running yet but i am following this thread closely and i am waiting to hear what the fix is........

Put a thermal clutch fan on it with a shroud. Half the time, electric fans are garbage on the street. The extremely minimal power loss required to run a clutch fan is far easier to live with than overheating the engine. Run a viscous fan with a shroud.
