Read the article by K. Patrick Smith on the subject. Pat was Dyson Racing’s long time crew chief, now retired, one of the best mechanical minds I know, former president of inliners international, and ran a pretty fast GMC powered race car a number of years ago. It’s a little bit of work to get them to run right.https://www.inliners.org/tech/tech4.html
On the other hand, and as an alternative, get a pair of adapters from tom Langdon over at stovebolt and install a pair of 1974 ford pinto Holley/Weber carbs. They are a progressive two bbl, small primaries and larger secondaries, threaded input for the fuel lines. They run really well right out of the box. You can also use the actual Weber carb, it’s the DGEV 32/36, essentially the same carb just no threaded input, uses a brass nipple.
Tom Langdon may still a carter/Weber carb, little smaller then the Holley Weber, that can also be used and will also run way better Right out of the box then the two 1 bbls.
