Since my Uncle had a Pontiac dealership (for 67 years) in this time frame, And I worked for him for a few years as a mechanic, Mr Forrest, our Chief Mechanic told me that GM never installed TRI-POWER parts on 1967 engines and The Development Phase of the Rochester 4 BBL Carb was several years earlier. Another BS story vs reality.

If you worked for an Auto Company in the 1960s you would know that the engine development time "start date"
for the components was YEARS ahead of the production year.
