Running hot!

Yes, you don't want to run the engine too cool it will cause excessive wear. I run a 180* in mine with shroud, fixed blade fan that sits 1/2 in 1/2 out of the shroud and the fan is about 2" from the rad. I also drilled a couple of 1/4" holes in the metal ring around the t stat. My engine runs right at 180* in traffic, cruising etc. even on 90* days.

EDIT: If you are not running a puke canister, don't fill the rad to the top, just enough to cover the cores.
