  I have a stock cooling system and just completed the Sierra Challenge without overheating. I also watched my temps via scangauge, it got up to 220 degrees on one long crawl but we were running the A/C. For reference 220 on the needle gauge is still in the same spot as normal operating temp. I think 225-230 is where it starts to climb. My truck typically cycles 195-205 degrees as the thermostat does its thing, if i demand more from it I'll see 205-215 the needle never moves. Having a digital temp gauge helps monitor things better.

Tested one of prototype radiators, seeing about 179-181 as normal temps and running the truck up a steep grade highway for 3-4 miles at wot  saw about 192f. 33's with 4.27 gears and AC on with busted AC fan.

That's excellent!  Interested to hear how it does in long steep crawls, I'll give you a call back today. I was just getting back into town when you called yesterday.

I noticed when I first got my rig, it would hover around 198* every day. (measured via scangauge)

However recently, it tends to sit at 202*, but it does creep up to 209 climbing grades, and at one point it hit 240* while climbing up white mountain in big bear.

I haven't touched anything, but I suspect me playing in mud got a lot of crud stuck between the fins of my radiator. I'm hoping a nice chemical flush and rodding the radiator will help me out.
