Dumb questions, I know, but I'm curious.

I currently have an 8BA Flathead using 3/8" belts/pulleys. I need to rebuild the water pumps, so I'm thinking of beginning to convert the pulleys over to the wide belts. If the pulleys are mismatched for a while, will either belt work?
If you are rebuilding the original pumps that have 3/8" pulleys like the rest of the system, what possible reason (that makes any sense) do you have to change them over to 5/8"?
