What would it be better for my car. An Aluminum High Flow water pump or a Cast Iron Water Pump. I have an Aluminum Radiator with an electric fan. I heard that the Cast Iron would do the job just fine. but should i really spend more cash for Aluminum.

I'd just go with a plain 'ol water pump. If the radiator is properly sized, you don't live in the desert, and everything's in nice shape, I don't see why it wouldn't do the job, and lots of people back when ran stock waterpumps anyway! Hmm....stocker $20, aluminum $100....hard decision
