I had an electric fan in my 88 for a little while, and it was a 95 3.8 ford Taurus fan. They are rated at 4500 CFM, so a higher amped alt. is important. I would suggest at least 75 amps. I had to take mine out cause the alternator went out so this was my down fall. Also the Taurus fan I think will have a hard time fitting with only a 2" BL, I had a 3" and it was a tight fit. Horsepower, it didn't make a difference, not a noticeable one anyway. I took a much easier route and just lowered my radiator three inches so I could put my fan shroud back on and have the maximum cooling back. If you want a taurus fan go here:
