horsepower

154k miles, black, very clean. RWD. mechanically seems well sorted and up to date on maintenance intervals and some replacement parts... brake booster, radiator, cooling fan, timing belt, water pump, goodyear assurance tires (a little oversized). no codes, just did an o2 sensor for 65 bucks...

I am interested in doing a electric fan conversion on my 4.7L. Anyone have any do's or don'ts. Tell us what you are using if you have done it.

Has anyone used or know were to find a 4.7L Underdrive pulley kit? I've tried a couple companies but they have discontinued them.
