i use a 96 thunderbird(had the 4.6L) electric fan from the junkyard, it's a bit thick so i only have about 1/4-1/2" of space between the actual fan motor and water pump pulley, plus i had to trim down the shroud of the fan and it sits a couple inches below the top fin of the radiator..but works extremely well, my car has never overheated with this fan, once the fan kicks on(parts store adj. controller, 50 bucks) the temp guage only goes down till it kicks off, great fan but probably hard to find, check ebay?
