FWIW, I am going with a Lincoln Mark VIII fan because they advertise 4500cfm! Those and the Taurus fans (for the 3.8l motor) are the most popular. i went a placed called dc control for the electricals. They have a ramp up and down unit and the sensors that clip right onto the radiator fins. I think the site is
www.dccontrol.com I also agree with those who say that too much cfm is better than not enough
Good luck with whoever you choose for a vendor.
