2004 F350 Engine Swap
 

Hey guys. I'm planning on buying a 2004 lariat f350 from a buddy for $4500 (I think I could get the price down $1000-1500), but the engine is blown. Other than the engine being toast, the truck works fine, and is worth keeping. The truck comes with a used engine as well, currently in his garage. I'm trying to figure out if this could be economical. I want to do this on the cheap, but it needs to be done right too.

First off, (I do not have a lot of mechanical know-how/experience) does anyone have an estimate to get the engines swapped by a mechanic? I would transport the vehicle. Would it be worth it to remove the engine myself and let them put the other used working engine in for me, how much would that cost and how hard is it? I also don't know how to test an engine to see if its worth paying money for to stick under the hood. I'm pretty sure that the engine type, being a newer model f350 engine, doesn't matter. I'm looking for practical info and quotes for cost. Thanks guys.

You need to be careful when changing engines because even Ford changes calibration specs mid year. Your best bet is to compare calibration decals from the original engine to the replacement engine. The days of swapping engines as done in the past are gone. Computer controls and engine build specs can vary quite a bit and it's best to get the correct engine when contemplating a replacement.

Are those decals on the engines themselves? I believe it is the correct engine, as it was taken out of a similar model and year, what do you think about having a mechanic come out and inspect it?

A second experienced opinion is always a good move.
The decals were on the valve covers and door labels.

Thanks man, I think I will then.
