Nuts & Bolts - The original Holleys used on the various Ford engines, like other carbs, came in multiple internal sizes.
The carb used for the 144 and 170 was the smallest venturi. The others used a somewhat larger venturi.
Unless the carb has a variable venturi design, then it may not be optimal for all of the engines listed.
I know of the unit of which you speak, but have not seen one, so I have absolutely no opinion on this one.
I know of other BRAND NEW DESIGNED FOR MODERN FUEL copy carbs, produced in various places in the world, that make wonderful paperweights (until they get dirty). They are also very useful if one has a strong right arm (or left, must be PC) and a rabbit problem in one's garden!
There are plenty of dirty old cores available at swap meets, or available from online vendors, THAT WERE DESIGNED BY ENGINEERS BACK IN THE DAY specifically for a given engine.
These can be rebuilt, and when rebuilt properly, will outperform any of the SHINY new off-shore carbs in all facets except looking shiny!
