In case you haven't, make sure you transferred over the plate that sandwiches between the pump and the timing cover. Easy mistake that's happened a lot. Hopefully this helps!

You could have gotten a bum water pump. Any leaking?

was there a spring in the old lower radiator hose? It was there to prevent the hose from collapsing at higher engine speeds. Did you transfer it to the new hose?
