The important part would be a detailed guide on how to re-enginer everything we have today, as well as the science behind it. Really, I think scientific knowledge would be the most impactful.

      If this was a huge operation with near infinite resources, I would send back a giant self sustaining compound with a general purpose factory. I think it would probably be possible to sustain a roughly 60s level of technology indefinitely on a small scale until the rest of the world caught up
