Hi 66 Jetstar, I have pulled apart a standard rotation water pump. I don't think an impeller change out will reverse it. Looks like the housing is what determines the coolant flow.

That has not been my experience. I can't speak for oldsmobile specifically, but there were all sorts of GM engines that were in production when serpentine belts came out, and 95% required a reverse flow water pump, non of which had a housing change....
