    So, I may be doing a writeup on a navi swap into an 03 f150. Dads farm truck swallowed the stock 2v 5.4 at 203k. He and I have decided we needed to have some fun and do some modding. We built a custom 4.0 swapped 85 B2 5 years ago, so we're not newbs. Tag along for a bumpy ride. Snapchat-991156650.jpeg

    Still waiting for room in the shop. My brother has a 99 with a dead hole, so he's fixing that. Been looking at the diagrams between the two. Everything on the Navi harness for the most part looks to interchange with the f150 harness...

    I'm interested. I near bought an 03 a few years ago and was thinking of doing a similar swap.

    I've seen a few people have done it, but nobody had followed through with a writeup. Never figured out why, they look to be stupid simple.

    Spent some time today at dads shop! Getting little brothers 2v prepped for install on his 99. Should be drop and go at this point.

    Decided to put the 4v on a stand and go at it. Found some things that concern me, but I dont think its catastrophic.

    1. Thrown cam follower in the passenger head. (Removed lash adjuster and tested it, checked out good.)

    2. Someone put SOHC primary guides/tensioners in it. I bet this thing rattled like a SOB! Currently deciding how to correct it, as it's a low budget farm truck build.

    3. For those that are wondering, with some determination, and a dremel, you can put a 2v coil in a 4v head. (good thing I've got spare 4v coils laying around.)


    My father was all sorts of wide eyed when I started pulling the valve covers and timing cover. His exact quote, "how in the f--k did you time the engine in your car with all of that chain?" I just smiled and laughed! 20190819_190229.jpeg 20190819_215434_001.jpeg 20190819_215323.jpeg 20190819_214709.jpeg
