help visous fan worth it or not???

im running all stock stuff steel pump stock shroud stock rad

im asking because before i spend 40$ on having my fan powder coated and spacer
that runs at all times sense there no clutch if im better off to buy a viscous fan for the hp and fuel and what ever other gain ill see or if there just a bunch of trash and there not really any gain


I took a fixed fan off my 70 340 and put a Mopar viscous one on. Running stock rad and shroud. I am happy with it. Less noise with the cluch fan.
