Worked through the same issues myself. I'm running a 428FE and now have the Zirgo 3000 CFM fan and a larger radiator with a shroud and running 90-95 deg C on a 100F day.

I also had the engine dyno'd and found out it was set up wrong out of the box. Re-tuning dropped the engine temp by 40 deg F and is now spot on with A/F ratio, etc.
