Do you know if the Ford Taurus fan will be slim enough? ALOT of people run the 3.8L Taurus fans in their cars. I have one in mine, keeps it at 180 even in traffic. Also if I'm correct they are 2200 - 2300 CFM and you can pick them up at pull-a-part for about $15 iirc. I can measure how thick mine is (no homo) when I get to the house after work. Here's a link to how mine turned out, of course the radiator setup in my car is different than yours but you get the idea.
