It's from a 1966 Ford. I am not sure of the rest of the numbers.

Before Ford introduced their fine Autolite 4 bbl carbs, they used many Holley 4bbl carbs.

These carbs usually had detailed changes from the common aftermarket performance carbs that we know from Holley.

These carbs were manufactured for specific V8 engines in specific applications, so there are some differences in vacuum ports, float bowl vents, jetting, power valve specs, etc.

Measure the diameter of the throttle blades. Most Holleys made for Ford had small blade diameters; approx an inch or less. These carbs did not flow too much, usually 400 - 600 cfm, depending on the design.

IMO the aftermarket universal Holley carbs are better for performance. Your Ford carb is really only useful if you are restoring a '66 Ford to original condition.
