Might bump that idle speed up a little too. I think mine idles about 650.
Also, my fan is the old stock X fan, but it is about 3/4 to 1 inch away from the radiator.
If you can't find a spacer that thin, might make some spacers to go between the radiator support and the front end of the truck to get the radiator closer to the fan.
Fan shroud would help too if you can find one. But my truck doesn't have one. Runs 190 or so all the time.
