Vaccuum was checked with the car in neutral. Just called my mechanic to find out what the timing is set at and will post shortly. I called Comp cams and asked them what the vaccuum should read and their response was between 8and 12. I wanted another opnion. Based on the specs I have given, what should the timing be set at. I have been told that if it is too far advanced, it will cause too much "ignition" and damage the engine. If so, what is too much adn what is acceptable??
