convert from clutched to non clutched fan?

Hey all, in my quest to find a new radiator, I was wondering if I could gain some of the extra room needed if I converted from the cluthed rad. fan(which I have) to a straight running fan with no clutch. is this possible? is this more expensive than getting a heavy duty rad. I do have a serpinting belt, which causes the water pump to run in the reverse direction, if it matters.
thanks

Re: convert from clutched to non clutched fan?

The down side to what you are proposing is more drag and noise. If you really want to go to a solid mounted fan, a flex fan is the best option, but not what I'd do. Your best option if you want more room is getting rid of the engine driven fan altogether and going thermostatically controlled electric.

If you do decide on a flex fan, stay away from deep water, if the fan hits water(or mud) it will flex right into the radiator. Thats another good reason for the elec fan, you can turn it off when needed.
I'm changing to a elec pusher fan to gain room to move the motor forward.

Re: convert from clutched to non clutched fan?

what is involved in puting in a electric fan. More exactly, what involved in getting rid of the fan and clutch? just unbolt it, and cut off the remaining shank on the water pump?
thanks

I just unbolted and removed the fan and spacer but left the waterpump shaft the way it is.

Re: convert from clutched to non clutched fan?

I agree with WC, electric is the way to go. I just bought a 4 core rad from Auto Zone and i still have my strait mounted fan off the water pump with about 2" to spare.
P.S. the 4 core rad is great. I can't get above 160 degrees on my 258. But i'm still going with electric because of the advantages when hitting water.

Doesn't even get to 160?? That's a little too cool for a 258.

When you unbolt the fan, you'll have to put some shorter bolts back into the water pump to hold the pulley.
