Help needed for diagnosis - pictures inside

well my suggestion is to hook up the vacuum advance :D

it's there to help during idle and steady highway cruise.

it will have no effect on wide open throttle, it's inoperative then.

so use it, i'm betting it will help your idle out. if you have a really big cam and low vacuum they dont help so much however. they get weak with low vacuum so never actuate.

do you have a vacuum gauge? can you borrow one?

Car has not been out of the garage yet, I have vacuum advance unhooked at the moment to set timing. When I say it is idling rough, I mean it looks like it might break a motor mount it is shaking so much. I do have a vacuum gauge and will be using it after I put in a new set of plugs and possibly swap out the MSD box. The one in the car was used when I got it but has worked well. But I have a new one on the shelf I have had for several years, gues it is time to break it out.
The cam is a 268 voodoo. Should have a slight lope but nothing radical.
