Help 360 getting hot

I have a similar problem as you, with the same radiator. Im starting to suspect the radiator isnt up to the task.
Couple other thoughts.
Use a 8 blade water pump instead of a 6 blade.
Try a fixxed fan instead of a clutch fan.
Use a smaller AC upper pulley. Spins more ?
Go to a 160 free flow thermastat.
