fan dilema

[FIREBALL]

ok guys need some input i know the flex-fans are not a fav of some on here i myself have never had a problem with them but you never know. Anyhow i was wanting to change over to a clutch style but i notice a problem or maybe im just not thinking clearly. Right now i have a 350 a/c style with appearing to be a 3 or maybe 4row alumnium radiator (bought it with it installed) already. It has a short water pump on it and the v-style pulley setup. Now as it its now its got a 2" flex a lite fan spacer on it and a flex fan that goes somewhat inside the shroud maybe a inch or little more. My question is being as it has that spacer and all if i go with a aftermarket fan blade can i run a clutch on it or would it be too much strain on the pump? If igo back to total stock it wount be close enough.....from what im seeing i dont know though Im in a deliema because should i run a steel hub with stainless blades or a total steel design. I just dont want to put too much on the pump and would it work is another question anyhow see the links below and i apprecaite everyones input cause it will help me decide for sure see the link below...

You are trying to mix and match two different styles
of fan. The link to the clutch you have is a replacement for an oem clutch but none of the links is for the correct fan. Those are
All the same type of fan that use anstationary solid non clutch spacer. I recently posted a wtb for an oem type fan to replace the flex fan that a P O installed on my truck. Here is a link to my wtb ad and some photos of what you need.

You don't use a fan clutch on a flex fan you use the 2" spacer. The last 2 fans say there standard blades so I would say you could use a fan clutch on those 2. 1" or a little more is about right for your fan sitting in the shroud. You don't want it all the way in or allthe way out. I think a little less than half.

None of the fans listed will work with a factory style clutch. The fan will have to have an open center around 2" in diameter. Take a look at the photos in the link I posted.
