You're running an 11 bolt pump, make sure all the correct parts are in there. You're heater hose is incorrect as well, it should tie into the back of the PS cylinder head, not that it'd make a huge difference but...
11 bolt seems to be more consistent cooling, although you'll get arguments on that. Loose the sheetmetal shroud and get the fan positioned right. Can't tell for sure but it looks to small a dia or not centered for the plastic shroud opening.
And it looks like you're 1:1 crank to WP pulley, an overdrive (smaller on the WP) would definitely help. Probably be easier to find a two groove pulley.
