Well, this isn't what you want, but I have some information. I will be running a fan from a 3.8L Taurus (I think mine was in a '92). It took a while searching the junkyards, but since I enjoy going to the junkyard I didn't mind. The price was also right at $25.

Here's a link to a web site explaining one way to install the fan. I don't subscribe to the quick easy philosophy of sticking things through the radiator to attach the fan, however. I think it would be well worth anyone's time to spend a bit planning and fabricating some metal brackets instead.
I believe the Taurus fan is a two speed unit capable of 2000 cfm. Should be plenty for my 351C that I will be installing. I also plan on using a Jeg's universal Ford radiator. I measured my '70, and it looks like it will fit fine to me.
I hope that helps you.
