If I read correctly, you were considering running the electric pump as suction from the water pump inlet to the bottom of the radiator. I was taught that radiators are hot top(inlet) and cool down(outlet) due to thermodynamics. Crossflows work the same, but I don't see how putting the "hot" outlet at the bottom is beneficial. I get reverse flow in the block, but not the radiator. I could be wrong.....
no, i was not interested in doing it backwards or reverse flow like someone else had mentioned. it would be easy to reverse flow an engine, but i'm leary of it on castings that weren't designed for it. No need to try in my instance, anyway.
