Stewart or Edelbrock waterpump?

[Chris_H]

Ok I just got the OK from the wife to get some stuff for my cooling system befor the summer heat gets here with its 105+ degree weather. Which water pump would be better to run between the Edelbrock and Stewart? Also I will be getting the Heavy Duty fan clutch and heavy duty fan. Can't get an electric because I don't have the money for a new alternator upgrade. Unfortunately I will still be using the stock radiator too. Any help will be appreciated.
