Also, Chev had planned a 3x2bbl small block engine for the '67 Camaro that was nixed before production. Several of the assembly manuals had pages referencing that engine that were marked "cancelled". I do not know any particulars about the internals, but it used the same chrome valve covers as the 350 option and a triangle air cleaner like the tri-power Corvettes. '67 was the first year of the 5-year 50,000 mile warranty and that may have had some bearing on the factory offering those performance engines.
