Who was addressing you in my post? I certainly wasn't. Your problem was already solved well before that. I was simply pointing out erroneous information in a photo posted by a fellow member. It did not involve you in the least. Also, you completely missed the point that, because I have two blocks cast on exactly the same day that were possibly installed about a year apart, the so-called experts who think they can nail down a block casting date to an exact day are blowing smoke. I say "possibly" because if you'd kept reading, you'd see I later added that the "72 block" does not have a year stamped in the partial VIN, so it could also be a 1973 block.
A former local auto shop teacher worked at Hamtramck assembly from late early 1969 until the end of '72. He swore every 340 was orange. He knew--he was there. He was also wrong. So, congratulations on your retirement but sorry if I don't consider every former Chryler employee some kind of authority. It was just your source of income, not a research project. I worked in foundries for quite awhile, but I couldn't tell you a single casting number for which I made hundreds or even thousands of molds.
Just because you started a thread doesn't mean every single post pertains directly to you.
