which electric fan will fit?

Seen the mid 90's Ford Taurus fans used on stock radiators as well. Single fan but has high and low setting. Guys use the low setting from what I've seen (2500 or 3000 cfm on low. can't remeber exactly) and they say it blows away a single 16" Zirgo 3000 cfm fan in the cooling department. But the catch is that the fan and shroud are fairly thick I think whereas the Zirgo (ZFB16S) is slimmer. The Taurus fan is offset to one side which helps but I think that a little trimming could be required to clear the water pump pulley. There's an old thread here I'll look for but both the Taurus and SVT fans were recommended it seemed. And IIRC the SVT fans pull some pretty good amperage...
