I am running CIS w/LM2 on a 3.3SS engine in my 1980 SC. Having the AFR is really a blessing, making it much easier to get good settings. Once warmed up a bit, my engine idles at about 14.5, cruises between about 14 and 15 and goes to about 13 at WOT. Good strong idle with good throttle response. I did have to play with the timing and the air idle adjustment some to get everything happy. I am using XDi twin plug, crankfire ignition that is very adjustable using 4 setting knobs on the control box.
