[Woodz428]

It seems that everyone agrees that it is not a CJ block and you were deceived by the seller. One of the problems, I've seen over the years, is that most guys only know of the 428CJ and not the regular one.Since the CJ was the scourge of many a drag race at the time, when they hear 428 they automatically assume it is a CJ. If you didn't over pay fo it and it is in good shape it will still give good service or get your return to invest in a real CJ. I would contact the guy again, fraud would be a term I could think of and it wouldn't be too hard to prove,but it might be easier and quicker to re-sell and purchase the correct block.
