Steve, what is that other unber stamped on the block? Isn't that the engine production number? If so, wasn't it part of a sequential numbering scheme? If that's true as well, then shouldn't that number be related to some date range? Then you can see if the engine was built before or after the car was built. How do the dates relate on the block vs the car's build date? Jack, I'll try to get those magazine articles loaded up later today and link them in so people can take a look at them. The smog setup makes you think they were trying to prep it for regular production. You can also see the heat riser tubes for the air cleaner which would also be for a production engine.
