Good question and I really don't know the answer. The Taurus fan pulls a ton of air 2500 (low speed)-4500 (high speed) depending on which model you have. If you are running AC, oil cooler, automatic tranny cooler you obviously need more CFM. Adding a V8 to our cars requries more cooling too. You don't want to cut corners on this one, the results can make a daily driver a nightmare if you start having cooling issues in traffic. A few dollars here will be well worth it. The Tarues fan can be found pretty reasonably priced. And DO NOT use those through the radiator mounting things, they wil eventually take out your radiator.
