I picked up my new to me 85 f350 4x4 yesterday. Has a 94 IDI non turbo ENGINE, 4 speed with brand new gear vendor truck is from the south so it is rust free. Man are these IDI's cool or atleast I think so. I bought it yesterday afternoon and just got back from a 200 mile trip and it didn't miss a beat set the cruise at 70 turning 1900 rpm. What I need to know is what can I do to this performance wise? I know there isn't much and it already has a 4" dynomax exhaust on it. I plan on doing a turbo very soon. Any help is appreciated! Thanks
