The closer the fan is to the radiator core, the less the air flow looses from the fan tips. Your distance may be correct but in later years the distance is generally in the range of 7/8 inch or so. Remembering that the air flow loses increase dramatically with small increases in air gap, you might be able to get a significant increase in cooling by making a spacer to move the fan a bit closer.
