73' B3 340 Duster pro touring build

Ross - I am contemplating doing a remote water pump as well. But my car has a 440. I am thinking one way to do this is to use the single in/outlet style (PRP sells one as well as Meziere) and putting it in-line with the lower radiator hose and using the stock big block housing. Then, in lieu of the water pump, just put a machined block off plate. What do you think?
