Why are my distributor cap terminals burnt?

What advance mechanism does that distributer use? Pics?
The only picture I have is when I took the rotor off, but hadn't taken the plate off between the rotor and weights.

What's the actual specs of your build?
I wish I knew. Like Mattax said, it seems to be pretty close to a factory 440 by the measurement I got on the cam, but that's really all I know. Six pack, iron heads.

What I can't figure out is why I would only get 10* mechanical. I'm going to add a black spring tomorrow and see what that does.
