i think you dont need to change anything that is under the hood. if you want more power i think it is best to change some parts like your ford exhaust manifold
but that will cost you a lot of money changing parts which are not yet broken and still have some purpose. i think it will be best to lift your truck first then put some bad ass big tires then also change your muffler for added horse power but it is just a bit. what i like about mufflers is the sound that it generates! total bad ass! lol.
I get my parts from autopartswarehouse
,if you know better sites then send me a private message. I'm currently preparing for a restoration project. I will post a thread and pictures soon.
