Not in my opinion PP1RT. I am trying to sell my car through a classic car dealership friend of mine. I am asking $35,000. Mopar guys keep coming out to look at it but offer $27,000 to $31,000. All say if I can verify this is not a swapped engine they would pay what I am asking. My dealer friend agrees. if there is a way to verify that engine came out of the factory with that engine in it, or that the probability that it did, it is more valuable then a swapped engine. Both previous owners say the engine was not swapped. Just trying to find super high probability that they are true statements. it is a 68 or 69 block so according to this thread it SHOULD have a vin. Since stamping was supposed to start August of 1967. If it was swapped out of another car it should have a different vin. If not, then I am thinking it was a FACTORY swap. otherwise it would have vin numbers. But that is why so many questions. Im not an expert.
