I have a 1990 GT and want to know how to determine if the engine block is original. It may not be but I don't really know how to find out.
Also if it doesnt match and I have no receipts to verify it was bought legally, which I beleive it was, how will this affect me selling my car. I live in AZ. Would this be a problem in my state and what about other states?
Thanks for any help you more knowledgable people can share.
