Thinking of buying a Street Demon Carb...

I see that Jegs has the Street Demon Carbs on sale this week for only $281. I'm thinking about buying a 625 polymer bowl one for my stock 1969 340 4-speed Dart. I planning on using the factory air cleaner, but I have read that some people have had clearance issues around the electric choke using stock air cleaners. Anybody running one of these Street Demon carbs and are using the 68-69 factory air cleaner?
