Electric fans....
In Sandusky, OH, you might be able to get away with the Black Magic/Proform kit, but they really are marginal for our cars, especially once you've got a few mods.
In my opinion, you won't go wrong with these:
Lincoln Mark VIII
SN95 Mustang electric
Taurus (equipped with 3.8 V6 - late 80's-mid 90's)
Ramchargers dual electric fan
SPAL dual electric
The good thing about the OEM fans is that you can find them cheaply at the salvage yards. You will have to fabricate or buy your own fan control setup. I really recommend this one:

Good luck,
