Gordon, could you elaborate on how you use vaccuum WRT ignition timing? I
have a vaccuum guage in my 79, and would love to use it for tuning. As it
is, it's prtty cool to watch, but what "goal" do you tune to? I have
electronic KS ignition, so it may not work the same way as it does if you
have the cannister on your ign. dist. But I'd be interested anyhow...
