I have a 2004 f150 heritage edition and I was wondering if I could fit either a '03 or 04' lightning engine and transmission into it.

 

im sure it can be done. same bodystyle, it would help if you had a donor vehicle to pull all the parts from though. but after all that work you could probably just build the motor thats in your truck now better than the lightning motor. I think the harley davidson edition has the same motor as the lightning too.

 

I could build up my current one but its only a V6 and I was planning on dropping in a V8 instead. Just trying to get a feel for it before I start looking for said donor vehicle.
