Well first I would get rid of the 50/50 mixture. Use distilled water and only enought anti freeze to keep corrosion down ,say around 20%. Then add a can or 2 of water wetter. Make sure all the air around the radiator is blocked off so all air has to go thru the radiator. Decrease your timing a degee or so will help also. A good spoiler will help too (this helps the most when moving). I've got a 454 and it runs 172-180 all day. I have a flex fan on this one with a stock shroud.
Stock water pump, no factory shroud, yes cools back down in motion.

Thanks for your comments.
My 350/330 had overheating problems. I was using full synthetic motor oil. I changed my motor oil brand to Rotella 15-40. T4. It resolved my issue. Temp stay 180° not 200-210°.
All new replacements, appear ok!
Sounds like your fan needs some sort of shroud so it pulls air through the whole radiator and not just the circular area it covers.
Possibly a dual fan + shroud set up.
I agree with F4Gary. That would be my next thing to try.
