What flex fan to use.

Hi all.I have a duster with a 318.Would like to use a fan clutch,but I can't because of radiator I have.What type or brand of flex fan do you use.Right know I have the slant six steel fan 7 blade.

Most /6 fans i've seen are 4 blade. If you're not running a shroud, a flex fan might no keep it cool enough.

This /6 had air.That's where the radiator came from

not sure on the best: brand/alum or fiberglass but FYI here are part #'s for 2 short clutch fans. trw fc-28 2.75" height, hayden 2765(not sure of height) listed for a jaguar

The BEST flex-fan to use is the OEM one ...with the rolled-over trailing edge. They WORK ...and they will flatten-OUT at higher rpms .. but they are heavy and can "tax" a v-belt if you want to rpm the engine up-quick.

Use what you have with a shroud if you are having cooling problems. Also look into the clutch and fan that the fan comes in from the back side of the clutch. the bolt spacing of the fan is different and has a large hole in the center to clear the clutch to water pump flange. may help with clearace.
