I have 98 f150 with the 4.2 in it. Thinking about getting a crate 302 to put in it. Has anyone on here done this

 

Looking at a lot of work there.

 

What all do you think I'll have to do?

 

Custom mounts, lots of wiring, and Advil for headaches

 

Custom guage setup to make it all come together. If it were my truck I would find a donor with a 5.4 and a 4r70w. Pull them both along with the pcm and cluster. If it has keys then you are ahead of the game. Install in your truck and enjoy the extra power.
