iginiton timing questions

Yes definately good reference kinda fills in some the gaps I am fuzzy on.

After work tomorrow I need to go out and put my hands on the car put this knowledge to work cause that is the way I learn. I can read a 100 things on doing this but it doesn't snap into my brain till I have hands on. Than i will probably come back with a million questions for you. :)

Distro is stock from an 82 Ramcharger. Is there a way I can tell for sure if its a smog distro? Being an 82 I would assume it probably is? If I had a smog and was running the init timing advanced would that create a situation where I was advanced to far or would that even it out or even slightly retard it?
