You can often find just a long-block with nothing on it for around 1200-1500, but then you got to find all the accessories and stuff its missing. By the time you get and find everything $3000 is a reasonable average total cost for used engines/trans with 50-75k miles.

PCM compatibility is not that big of a deal, other than you need to make sure you have a proper pcm relative to the year model of the car. The center connector goes to the body harness, and it plugs right into a v6 or v8 pcm, no issues. The engine harness is slightly different between a v6 and v8, with additional circuits and things in a v8. And then, internal circuitry to support the difference. Again, not that big of a deal.

So, a big challenge to a swap is in getting all the parts together.

I've done several of these swaps and with everything on-hand you need, it's not that bad.
Hello I have a question for you, I have a v6 2007 and I bought a 06 v8 donor car with everything on it and the keys is It possible to do a stright swap on it ? Or will I have to do some mods to make it work?
