Just as the title says..... my brother just bought the 93 F150 and wants todo upgrades. So basically what is the same and what is different........? Also can the air intake be changed to a fox style intake..... since I have a few of them hanging around? If not what is the best aproach to these F150's...... Any help would be greatly appreciated...... If there is lots of info on this site, what should I search for, I tried some different stuff but not much came up........or if another website is out there that deals with this stuff could one be recommended............Thanks
