Ok, I've posted a thread about this issue before and have gotten great responses, I've tried everything everyone suggested and it's still sluggish! I've put new plugs in it, new plug wires, new cap, new rotor and new vacuum lines! I set the timing, I rebuilt and adjusted the Edelbrock 1407 and adjusted the valves but when I take off it still sounds and acts like it's running on 7 cylinders! I don't believe I have a vacuum leak, burnt valve or flat cam lobe, it doesn't knock or smoke and the 3" exhaust flows fine! I've heard other vehicles through out the years sound like mine so I know I'm not crazy but I'm at my wits end hoping someone has had this same issue and know what my problem is?
