Sorry a typo on my behalf.
I already know that the number does not match the chassis.
What I would be interested in is where did this engine come from and what happend to the car it orignated from.
This way I might be able to match info from the donor car with the owners and/or mechanics and figure out what the PO and original owner knew.
In hindsight I begin to feel like I should have started my car search here.
Steve, in your role as a mechanic, do you have experience with detecting fraudulent cars like this??
PS. If nothing works out for me I might just start and maintain a website, that informs and provides legal forms for buyer and seller that can protect both parties and I will mention names of the parties involved in this case....
