Remote Water Pump for Small Block questions

according to BeCool radiators and others, as long as the square inches of the cores are equal as well as the size and numbers of rows, crossflow vs top down doesn't matter....

as long as all that other stuff is same-same....

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.....
