Clutch fan

Need some advice on putting a clutch fan on my 77 F259 with a 429. My current setup is direct drive fan which roars. I purchased a clutch but I don’t have enough clearance between clutch and radiator. Is there a different fan with a big hub that would bolt to back side of clutch that would allow mt to still use spacer and bolts that I’m using now? I have seen the big non metal fans with a large hub but need to be pointed in the right direction. Thx for the help in advance.

Yes you have to get the fan for the clutch it's different. the one on my 429 came off a Mercury with a 429 in it. I'm sure it fits many applications for Ford vehicles with A/C .

You may need a new shroud too I'm not sure.

I used a NAPA clutch, a Derale 19" fan and a stock shroud with an aluminum radiator. Works great.

Thx 429SCJ, I have a working setup currently but the sound of a tornado from under the hood bothers me. I want to eliminate some hp robbing also.

Go to this site and find the shortest clutch with the correct bore and hub bolt circle for the water pump,,go to Summit and find the largest,most blade fan that fits the truck and the clutch.

Have be careful when getting the fan clutch. Replaced mine once and of course bought the HD replacement. It locked up tighter and at a lower temp than original, you could feel it pull down the engine when driving and very loud. Must have suck 5 or 10 hp. Went back to original and called it a day.
