I'm going to play the devil's advocate:

Personally, a vacuum secondary carb is not anything I'd run on a drag car if I had a choice. And converting it to mechanical secondaries is not a viable option, IMO.

The vacuum secondary isn't a deal killer, necessarily. But undoing another "carb guru's" mucking around well could be, depending on what they knew when they modified it. There are way more screwed up "modified" carbs out there than good ones. And the good ones don't just fall into your lap, ordinarily.

That said, do you have any history on this carb- as in, has it been successfully run on an engine in it's current state? Because if it's a modded carb that was a flop, you can chase some other guy's screw-ups until you're blue in the face, and still not get a decent performing carb out of it.

AFA milling the airhorn- unless you can do it or have it done for free, spend your money elsewhere.
