The Lincoln Mark 8 fan used to be the ne plus ultra of electric fan conversions as it was common, cheap, and could move a fuckton of air. Dim memory says 3500 cfm. Now it's kinda hard to get though, there's just not enough Mark 8's around anymore. Further, their power requirements are a bit difficult to deal with. They'll pull something stupid like 100+ amps on the initial start and fry most every common relay out there. Ford duty-cycled the things up to speed via the PCM and that's what they need to work well. Around 2000 there were some aftermarket controllers made but those are all long gone now.

After the MArk 8 got hard to get people went to the 3.8 Taurus fan, which flowed a bit less nut was still far better than any aftermarket. Then came the LT1 Camaro dual-fan that was a little weaker than the 3.8 Taurus but came in a shroud. At the time SPAL was as much of a joke at this as anything chinese.

Personally, removing the clutch fan was a mistake if for no other reason than you know the fucker is working all the time instead of wondering which connection failed this time. If determined to continue, then a couple design precepts are necessary such as there MUST be a shroud that covers virtually 100 percent of the radiator. The fan(s) need to be spaced by the shroud approx 1 inch away from the radiator so that it pulls from the entire surface of the radiator. Engineer you wiring harness for the fan(s) to be able to supply in excess of 100 amps and watch some youtubes on how to make quality connections. You'll have to buy a few professional tools too.

I say put the factory fan back and don't let yourself get beat by a piece of plastic.
