My guess would be that if it did not come on that particular combo or carb than your not suppose to use it.

I have several NEW bases and adaptors to make this type of set up almost the exact thing in the picture---$40 shipped UPS to your door-- let me know by PM please if anyone has interest in them--- you will have to fabricate the attaching rods to hold the base in place but that should'nt be a problem---we made one up in less than an hour

The written rule does not specifically exclude an adapter that is simply sandwiched between the air horn and the air cleaner base. For example, Caddy Sevilles, etc. used a riser type adapter, although it did not change the mounting diameter. Now you just need to get NHRA to follow your logic. . .

anyone have one of these for a rochester?? I would like to have one.

Late 70's/early 80's small block Chevy pick-ups used an adapter/spacer ring right below the air cleaner base. It was about 3 inches high with a tube for a crankcase vent hose. That would lift things up, but then hood clearance might be an issue.

Yes, the pickup adapter was taller than the Sevilles used. What would be needed here is essentially a slice of a big steel funnel to change the diameter more than to raise it up.
