Ported Vac or Manifold Vac

.... Before the thread disappeared, I had provided info & the OP asked where the thread had gone because it contained useful info, some of which came from me. I have also provided many links from a wide range of sources on MVA benefits, in a thread that is about man v ported VA.

the thread never disappeared, and you'd know that if your lust for manifold vacuum and articles about pontiac motors along with highlighter and annotations didn't leave you blind to that fact.
