Vacuum Reading

Is 20" enough vacuum? I've plugged everything but the main brake line. Seems a little bit low to me.

Maybe a bit low, but you should be okay.

My 82 and 85 has 21 mmHg and 22 mmHg respectively with the brake line plugged.

I agree, you are in the ballpark.

21 mmHg is barely 1" Hg.

It is relative to altitude. I think I get around 18 in Denver.
