elec water pump

Any of u guys ever run or tried a 50 gal. elec. water pump that fits in the stock housing ? I was wondering about the water flow being fast enough, or too fast to help,cooling a r/b stroker. I like the idea of running the pump after a making a run at the strip, on a street mostly car.
I would just hook one of these to the heater hose or bypass hose to circulate the coolant between runs along with a supplemental electric radiator fan. This way, you can put them on the same circuit and flip the switch after a run and let the electric system work to cool down the engine.
