George I agree with you I purchased the Edelbrock just based on your picture.. Once I recieved it I inpsected it for my self. With my mechanical backround its a hands down reason why your paying more, is just for just the impeller. The wieand pump is not an impeller, its a blender, the Edelbrock will perform and increase flow all the way thru the pump curve. Ok now we are into gpm and velocity thru the radiator is a whole different theory for another day. Some say too fast and it dosent transfer the heat. My expierience has been quite the opposite.
