I'd like to hear more about why the Tiger water pump is unique versus 
the standard aftermarket aluminum pumps sold for Ford 260's.  I'm 
rebuilding my engine and have obtained a Carter pump from a local 
supplier.  Visually comparing the new pump with the old pump, I can't 
see any substantial differences.  But if there are, I don't want to 
install something that will adversely effect the engine.  I'm spending 
too much money and time to have that happen!.
