Thanks, a Jewlers loop might show something, but I did take the pictures of the top of the pad with a Nikon D80 in RAW format, zooming in there appears to be nothing stamped.
Could someone have purchsed a 302 DZ from GM in 1969 to go racing, hence no VIN would have been stamped on the engine? Or were there privateer teams that might have gotten an engine out the back door. If so there must be other examples of non stamped engines out there, perhaps in historic race cars, museums, private collections?
Anyone have any ideas, assuming of course that my block was never stamped with a VIN.
