Electric Water Pump info please

Chief;
I don't know if you are really a mechanical genius, But you do put forth a well reasoned and well organized point of view. Taking cost out of the picture,the limitations of running without a thermostat, take the electric water pump off the table.
I do intend to run a good cross flow rad. with a set of electric fans off a taurus. They move alot of air and I can pick them up all day long for about $50.
Thanks for the info
Andrew
