ive got a 2003 f150 4x4 with a 4.6 2v 190xxxmiles 6"lift and 35" tires running 4.56 gears. i found a complete 5.4 3v engive with computer and wiring harnace and tranny with 46k miles. how hard would this swap be?

 

it'll be out of your league...

 

3v swaps arent real practical and I dont think is a real smart swap anyway. 5.4 3vs dont seem all that reliable to me its an engine I plan on never owning.. Find a 2v 5.4 that would easier and more reliable and all.. There is a guy who did it here on the board if you search you'll find answers..

 

If ya dont mind me askin why do you say that about the 3v? this is purely curiousity.
