250 P/S help

Does anyone know if the p/s pump for a 250 is unique, as far as the alignment of the pulley with the other pulleys on the engine. I was installing my pump last night and after it was mounted, I discovered that the pulley does not line up with the water pump or crank pulley. Also, do I need a 2-groove alt. pulley? Any help would be appreciated. I know this is a common topic, but I tried the search function and could not find anything. The other issue I am having is my coolant temp is running hotter than it was with the old water pump pulley. Is there a big difference in the diameter of the pulleys? I was
thinking that the w/p may be turning slower if the pulley is larger in diameter.
