Train wreck, I need to stop responding by tiny phone screen.😳🥲
I was going by the engine casting date! B 1 7
If it was a CE engine from that time, it would NOT have gotten stamped. End of story on that. If it was a warranty engine, there will be some information stamped on the underside of the starter mounting pad area with the assembly plant, month and year of assembly but that's it.
I can't tell from the pics if it was ever stamped or if it was decked and modified. Doesn't matter.
Bottom line. Engine is not original - it's a 1967 engine in a 1968 car, so no go. TH is not original - those were only installed in big block Camaros from 1967 to 1969.
