Any experience good or bad with clutch fans on your mopar?

Thanks guys, i was more concerned with if there was any issues anyone had with running a clutch fan, just trying to weigh the pros and cons before i decide to make the switch
I put a non-thermostatic clutch on My built /6 '72 Swinger, but on thinking about it I loosened ALL of the eng. & trans mounting fasteners & pried it back as far as it would
go, held it in place and cinched it down. As far as function, I wouldn't run anything else off the front of a water pump, period. Electrics should not be inadequate, but they
are usually not installed & activated properly, incl. sensor placements.
Make sure the fan You are using is not damaged, it will cause the pump to seize &/or fracture the shaft, I have experienced both.....this is the same for non-clutch units too.
I used My Pop's '76 heavy 3/4ton GMC 4X4 to go get My '64GT 'vert in OK, I bumped the timing up 3* from the spec, tuned-up, new hoses, 195* thermo, & added a clutch
fan to top it off. That 350 4bbl. pig never did better than 12mpg, but My neighbor & I almost touched 14mpg on the way out, and avg. ~11.75 draggin' the car back. I was
able to make it to around St.Louis before I had to step up to "Silver" grade, saved Me $150 in fuel on that trip,(fuel was high in march '08). That truck definitely runs better.
