Fan too close to radiator?

On my 66ā€™ 273 with factory radiator and water pump, Iā€™m running an early 2000 style Dakota fan and clutch. Fits diameter wise for the factory radiator and the factory metal shroud. You need a shroud. 22ā€ radiator needs all it can get to pull air thru that small opening. The clutch fan is quiet and works well.
