Which fan are you a "fan" of?

My new radiator won't fit in my '66 Barracuda, that has a 360, .060" over (thinking a tendency to run warm until proven otherwise), in it. The 360 has a viscous clutch fan on it and they stick wayyyyy out there in terms of a 360 in an early A body. I need to do something different. I lack around 3/4" of an inch or so of clearing. My options as I see them are a bolt on type flex fan with no clutch, or an electric fan. I installed a Painless wiring kit, and still have the wires under the hood. An electric fan may be a "breeze" to install. Is a no clutch, bolt on flex type a bad idea? Do I need an electric fan?

Thanks FABO. I know I have been wearing you out lately, but I'm close, dang it!:blob:
