I think he's probably talking Lightning 5.4 or Cobra 4.6
If you wanna do it man, go for it. It will be expensive and difficult. If you're not a pretty accomplished mechanic, I hope you have a DD to get around with, so you can afford the long downtime it will take. I guess the same goes even if you ARE an accomplished mechanic.
Also, it would be good to have a donor vehicle already so you can pull anything you need. Just having a motor won't get you anywhere. You'll need all kinds of little things.
To fit the 5.4L you'll need to move the firewall back, I know that for sure. You're looking at alot more than just a new motor also. Transmission, suspension, etc. plus necessary upgrades to brakes and such for the higher output motor. To get it all to mate up to your transfer case and 4wd, you're looking at even more complications. To be honest, I don't know that it would fit. You'd be looking at a TON of custom fabrication. If it COULD be done, I don't even know if it would be feasible. Then you get to dine into engine electronics and making it work electronically.
I'm not saying it's not possible, it has certainly been done, atleast in a 2wd. Don't think it's a "hey, I think I'll drop this engine in my truck in a weekend and go really fast" thing, or you're in for a world of hurt.
2003 FX4 Level II. Twin Shifters. Black. A few mods here and there.
