I'm putting a 53 Ford Flathead in a 37 Ford. I put the truck oil pan on it to clear the tie rod. I was going to use the Speedway Motors Water pumps that they have in their catalog for this swap. The pulleys on their pumps are for narrow belts. The crank pulley and generator pulleys on my engine are for the wide belts. What should I do? Run the narrow belt in the wide pulleys?? Help!!!
