I'VE SEEN A NEW TYPE OF RADIATOR WATER COOLER THAT IS ELECTRIC AND RUNS FROM THE BOTTOM OF YOUR RADIATOR. ANYONE KNOW ABOUT THIS?

The only people that I know that make a "booster" circulating pump (not to be used as a primary) is Stewart's Components ( www.stewartcomponents.com (http://www.stewartcomponents.com) ).

Inline Booster Pump:
Stewart' inline booster pump is intended for vehicles that experience overheating problems in low RPM situations. Since mechanical water pump speed is directly linked to engine speed, overheating becomes a major problem in situations such as parades, cruises, and stop-and-go traffic. The inline booster pump solves this problem by working in conjunction with the mechanical pump to create constant added flow to the engine block; the pump has been proven to increase flow by more than 300% at idle!

Any help for ya?

I'd wish someone a lot of luck crammin' that thing into the space on my '69.
