was common in the 70's up you could use it to set idel rpm up by wiring to AC switch
I'm not sure there is a way to hook one up to the 1100-1v
: It's pretty busy already around the south end of the carb throttle/choke/fast idle cam/pull off linkage (think they could have crammed one more thing in there?
)
To come at this from another direction, I'm wondering if you don't need to do some fine tuning on the initial & vac advance settings.
A couple questions to further the discussion/diagnosis:
1)Are you still running the Pony 1100?
2)What is your vacuum source? Manifold I would assume...if so is the scv port capped?
3)What initial advance are you running?

drops it from 1000 to 500, so I bump it up to 1100, now it drops it to 950...it's jumps from 900 down to 550
It almost sounds like when you tune the idle high enough to get out of the idle circuit (above ~1000rpm) the load is not excessive enough to bring it that far down (1100 to 950).
I wonder what adjusting vac advance and initial timing would do for you, given your bigger cam and DUI which needs a different vac source than SCV (I'm guessing you already knew that).
What about increasing the initial advance and if you experience pinging under accelelaration dial back the amount of vacuum advance the DUI is seeing (is the DUI vac cannister adjustable like others?). It's very late, so if none of this makes sense in the light of day, I'm going to claim sleep deprivation
Good luck!
