which raises the question: why not start with a navi motor? The answer is: the gains won't be worth it. is your 2v trashed or are you just looking to do the swap?

Your right, I was oblivious to the availability of the Navi 4v, my first FB marketplace search with 100 mile radius brought up 3 viable low buck candidates.
Yep they're out there but a word of caution: they do not make the power you think they would. I had my 4.6 rebuilt with stock parts (except for the arp hardware in the bottom and the flat top pistons) and with full exhaust, tune, jlt intake she puts down 323 hp and doesn't stop making power till like 6K. From what i understand a head/cam package, full exhaust, and tune, would produce similar (or better) results with a 2v without all the swap hassle.

its a lot less work, probably similar cost in the end, and you'll get something that pulls all the way to redline. i'm a broken record, i always suggest this to people considering a swap because working on 4v engines in the mustang bay SUCKS dude.

With my stock cobra H/C/I on a navi 5.4 block it should make close to 400, probably will need injectors . Im gonna do a low end rebuild, the navi 5.4 should come with a forge crank years 99-01, forge flat top pistons and forge rods, itll be one hell of a engine, down the road im gonna run e85.
