Can too much timing cause this noise?

Say the balancer had spun and you didn't know it or something like that. Could accidentally having waay too much timing once the mechanical advance kicks in cause the noise in the vid? It's not a mopar but I'm trying to help a kid with his first project (sbf powered rx7) and it's difficult trying to do it over the web. He's asking for help on another board, but since most of the guys (90%) use EFI and just pay a tuner, he's not getting much help. I KNOW the knowledge base for this kind of stuff is strong here so I thought I would ask. What do you think?
