I would have to agree. They did make conversions back in the late 60s and early 70s, that I installed for a few people, it basically piggybacked the front nozzle with a longer set that fed through holes you would drill in the air horn. It used a gear drive to the secondary plate. But I don't recall them ever being offered by Holley on a carb. If they did, it was dropped when the double pumper came out.
