Thanks Mongo, that's a great suggestion. Just hard wire the fans from the start to see if that helps.

My GM ECM has a wire output for fans and that is what I am currently using. I took that wire and wired them to the two fans. Those two fans come on around 200 deg.

I agree, the LS run hotter and seem to make more power with some heat. My only concern is that the temp never stabilizes. I just keeps getting hotter. I shut it down around 220 as I am a bit skiddish after Mondays trials and running 20-30 deg warmer than that. I am fairly confident it will keep climbing and never recover.

On a side note -

Any recommendation on ECM reader? I agree BR3W CITY, I should probably read and clear any codes. That might help diagnose as well.
