You can throw tomatoes if you want, but I am using a 1/2 in belt as a compromise between the two. My engine is a 53 car with narrow fan and crank pulleys and wide belt truck water pump pulleys. Seems to work OK. Not ideal, but for now it gets you going. Will probably convert the water pumps to 3/8 later, if they can be done without screwing them up.
