What does 7G6 mean?date manifold was cast at foundry. july 7 1966.
I searched thru some of the older threads (library) but could not find an answer to my question.I have a 1967 Convertible, 289 2V built 3/16/67 in San Jose.Intake manifold has code # C8AE-9425 B, with another three digit code below 7G6. I have read in some other publications that the C8AE-9425 was used in 1967. Is that accurate? What does 7G6 mean?
