Bad ground. Check the ground cable from the block to the chassis. I just fought that same issue a couple of weeks ago.

Stock car doesn't need a 180 t stat it may run too cool with it actually . If blower is an idea then I'd do it . Like hoopty said check the ground . And also that the t stat isn't in backwards . That will cause it too

in general overheating when the car is due to poor airflow from a clogged radiator, bad air deflector, or a stuck thermostat. Overheating in traffic is a bad fan,, waterpump

If your radiator was clogged up, wouldn't it be hot all the time? I have a Champion 2-core radiator on mine. It was cheap and works really well.

Im thinking partial clogged thats why i think it gets hot when driving...cant keep up with circulation...But when i come to a stop it cools back down...I could be wrong...unless the water pump is no good...or the wrong one?

Definitely all possibilities. Check everything. The good thing about a cooling system is none of the parts are really expensive, so it makes sense to replace anything that is remotely suspect.

flush the system, refill with new 50/50 and make sure to burp the system and then go from there.

From experience... You HAVE to burp the system. I really like the thermostat housing with the burp hole. I used an old temp Guage sending unit with the head cut off and hollowed out with a hose clamped to a bucket. Works burping the system super simple

To force out the air bubble. It's harder to do than you think!
