Is there anyone in your area with experience tuning of old carbed Mustangs with V8s? Essentially the same carb. Look for vacum leaks too.

The more I read and learn about his issues, the more I am inclined to think that my problem may be related with the vacuum system on my car. I had at least one leak through the 4x4 selector switch and one of the mechanics I used in the past disconnected something in the engine bay to plug the vacuum at the 4x4 selector. Maybe that may have impacted other things and possibly the "vacuum advance" on my distributor?... Anyway, it sounds like I will have to meticulously check and replace all the vacuum system hoses.
