Robby,
Jack brings up a good point. What year is your truck? Depending on just how much you have invested, it might make more sense to just hunt down a 5.4L. However, if the 5.4L conversion is the route you decide to take, a LOT is going to depend on what year the truck is. Switching form a 2V 4.6L to a 2V 5.4L isn't all that bad. Switching from a 2V 4.6L to a 3V 5.4L opens up a whole world of problems. Let me know what we're working with here and we'll see what advice we can offer. Take care.

Jack and Bill,
My truck is an '02 Screw w/165k miles. I would love to get into a new truck but I don't have that option or being able to afford a payment every month, so upgrading was something I really wanted to consider. I'm staying with the 5.4 2v family because I hear it is much much easier than going to 3v. I hear that I have to have a 5.4 tune for it to run right. Does that mean that I can plug in a tuner meant for a 5.4 or does it go beyond that? I need to act on what I'm going to do in the next day or so, so I am counting on you guys to help me decide on the 5.4 or the 4.6. Thanks Rob

If you have a 4.6L 2V then stick with that. The only gains with the 5.4L 2V is a little bit of hp and some more torque.(Can't find the #'s right now)
But if you do have some extra cash and can find a new or used 5.4 2V then do go ahead with that option. Make sure to get the related components with the motor. A salvage yard may be your best friend.

I'm going with the 5.4 for sure.....I found a mechanic that says he can change the motor from a 2V to a 3V and will guarantee all his work. He's an engine builder for a local stock car team in my area and I hear he is good.

I hope he knows his Fords. Just being curious, what are the major hiccups with going from 2V to 3V?
