I am looking for the red plastic FAST IDLE CAM off a 1985 Holly carb E5HE-9510-DB, LIST 50259). (similar to Holly part 45-376 but with an adjuster screw)

Or will it be easer to change carb and remove that excessive anti-pollution plumbing the F250,460 of that year had. If so, any recomended sites on do it yourself anti polution strip-out?

 

The fast idle cam can be ordered at most any part store or call Holley and they may send it out for no charge.

I just put on a Weiand Stealth and Holley 750 with electric choke. At that time most of the emission hoses went in the garbage along with the stock intake and air pump. Mine runs very well now.
