I have a 440 Magnum converted over to electric ignition and a 750 cfm Edelbrock carb. My question is: do I hook up the vacuum advance to the distributor or should I cap it off? And if so, is it best to run the line to the left (if looking at it from the front) upper vacuum nipple or the right lower nipple on the carb? People have mentioned that it should be conected to the upper, I have seen some on the other.

This has confused me for a long time.
