the real issue with 6paks is the screwed up idle circuits. if all your doing is racing maybe you can just do the basics, but for good street driving you really have to go after the emissions built into the circuits.
Could you elaborate on this statement. Since this is my thread, I guess it’s ok to highjack it. I have to agree six pack are harder to tune than most. The factory plugged up the idle adjustments screws for the outboards and the center metering block can give lots of trouble with the idle well tubes. The new bilet metering blocks really help the idle circuit, but they don’t look Stock. I’m all ears.
