This was discussed recently on another forum, and in general terms, I came to the conclusion that the criteria for the factory installation of a Holley carb on a 69 383 Road Runner (possibly Super Bee & Charger as well) was the cruise control option - which although rare, was indeed available. A/C did not seem to be a factor, as many A/C units were built with the AVS.

6bblgt: Are any of those Holley-equipped sheets you posted coded for N88 "AUTO SPEED CONTROL"? Very curious on this.....
