NOS Chevy "factory high performance" 307 engine?

[lowmile]

I'll get the pad stamps tomorrow. A few years back I purchased two NOS LS7's out of the same boat dealership. All of these engines have been in the same spot for the last forty years. I remember seeing them when I was in high school. He's about ready to pack it in. I also purchased a complete (down to the date coded plug wires) 427. It came out of a station wagon that was wrecked with less than 10k miles on it. He used it to pull boats!
