Steve, yep, as I stated above, Pontiac started calling the 400 HO the Ram Air III in 1970 in their internal documents, but not on the window stickers or on the order forms. Pontiac also never had hood scoop decals that said "Ram Air III", they simply said "Ram Air".
And yes, the 1967 Ram Air engine (later known as Ram Air 1) was a different animal than just getting the Ram Air option on a 1967 GTO. The 1967 Ram Air engine included the Ram Air setup, but also a different cam, better valvesprings, and 4.33 gears. They were sort of the shotgun version of a GTO, designed for dragstrip duty and street racing.
Cool cars.
