E fan and smog stuff

Hey guys what fan should I run on my 97 F250 with 460? What about the smog stuff is it worth taking off.
What about underdrive pulleys are they worth it?Thanks

The electric fan I had wasn't able to keep my 460 cool, the stock fan does. Underdrive pulleys don't help enough to bother. And Id leave the smog stuff on, or get ready to do a lot of programming on your ECM. Headers and bigger exhaust help a bunch though.
