Ported Vacuum or Manifold Vacuum?
I was adjusting my idle mixture today and speaking to a mechanic friend for some assistance to be sure I got it right. My distributer was hooked up to the ported vacuum port but my friend says it needs to be hooked up to the manifold vacuum side of my Edelbrock Performer. I switched it over and adjusted the idle and got the car running and performing well much the same as when it was hooked up to the ported side.
My question is which side do I need to have my distributer hooked up to for maximum performance?
