I would think an adapter for a carb might be a useful product. Example: I have a WCFB caddy intake that is a dual quad setup. I can’t pop for the $2,500 for carbs so I have to use a later style carb. Speedway sells a cast aluminum adapter, but the reviews are not that great. The castings are rough and ugly. I would like a nice 1” spacer that is aesthetically pleasing to the eyes, plus it would double as a thermal insulator.
