I think i found a 5.4 out of an 04 expedition not sure on the 2v,3v,4v but im pretty sure it will be a 4v i could be wrong im looking at it and the guy wants $700 im pretty excited to go see it tomorrow, and look foward to doing the swap i hope its a 4v but if its a 2v oh well ill still grab it cant wait to start building on it yay just thought i'd let you know where the stangs headed! should i worry about milage even if im going to take it to a machine shop and forge it?

 

if it is a 2004 then it will be a 2valve 5.4.

 

thats another thing im not sure on the year exactly either but its new enough to tell you how many miles to empty so im thinking 03-06, i havnt acctually seen anything with the truck i just know there is a 5.4, and its in a side wrecked expidition! i've been waiting to do this swap since like a month after i got my stang!

 

well, in 2005 they went to the three valve. you could buy some 4v heads and look into the differences between the expedition bottom end and the 4v 5.4. I don't know what your plans are with it but you want to make sure you have a solid motor when you're done.

 

My plans are to build it for nx, i just rather start with the 5.4 then a 4.6. But i think $700 is a good price, Im planning on port and polish the heads, Cams, rods, pistons, etc. A full build and then later down the road a 100shot

 

If you are going to have forged internals, ported and polished heads and cams you need to run a bigger shot of giggle gas than a 100 shot! I'm guessing you could handle a 200 shot easy.

 

Well its my dd so i want to take it easy on her, But i probably will run a bigger shot how much hp could i see with forged internals and a 200?

 

not sure about the nitrous but the stock numbers for the 2v is 260 and the 3v is 300. I can't see you gaining any horsepower just be having forged internals.

 

with the heads and cams, that should bring me some numbers i hope

 

are you talking about upgrading to 4v? I'm not sure you'll have much luck finding performance 3v heads for a 5.4 unless you can put heads from a 4.6 on it. that is the same situation for the cams. You may be able to have a pair of custom cams made somewhere.
