A vacuum advance is one of the most important things to use if economy is a priority!!! I've linked to a page w/info on timing, etc. earlier (on another thread), but here
is info on the vacuum advance that may help. You should take a look at the entire article, for that matter.
Be sure the advance is actually working. Often the original vacuum advance units are no good by now, being as they've not been installed on an HEI distributor for many years.
