I think I understand what you are looking to do but I dont think it will work.

If you use a L99 Water pump the outlet comes straight out toward the radiator near the pump pulley. If you then install a truck pulley and fan you wont be able to install the upper radiator hose as it will hit the fan blade.

I think thats the reason the truck pumps outlet is on top, to get over the fan and shroud.
