I don't want to ask anyone to do more work-believe me, This is a great place.
But after all this time here, it seems like YBF could have a FAQ section for instant answers for yblocks. Example
"How do I tell if I have a 312 or a 292?" or what are the torques specs for the intakes manifold?"
"How old do you think the "hoosier" really is?

sorry John just being sarcastic on that one, but what about it?, and how could it happen? Just a thought.
From what I understand one could also do Wikipedia section or site for this purpose Or a "knol" possibly. Again, just thinking-I better get back to what I'm supposed to be doing.
On second thought-I volunteer to prep example illustration, diagrams & photos to go along with it if you want, if you want.
