I am guessing that 8867 is the air horn part number. If your carb has 1406 stamped on it, it is a 600cfm according to the Mustang forum post.
Thanks just lo0ked
the front carb 1404 0813, assume rear is the same. Perhaps they are 450's and The linkage should be adjusted to run both and it will really wake up. It runs fine now and prev owner said he adjusted for gas mpg. Dean

500 cfm according to the one for sale on ebay, which indicates the second one should be needed when 355cu.in./1728cu.in./cu.ft. are turning 4866 rpm with a 4 cycle engine (every other down stroke is intake)??
Essentially, if the secondaries of both carbs have a counterweighted air valve above the venturis, the engine should run on the primaries (of both carbs) and part of the secondaries as it approaches redline at WOT. The air valves should regulate the secondary openings according to manifold flow.
PS what king of rad is that, and does the car have a hood scoop? I can't tell from the pic.
