Hmmm. So Pontiac built, in your opinion, 1355* 1969 Ram Air III Firebirds (excluding Trans Am, which were Ram Air by definition and construction) and no H.O.s? That is inaccurate.
It's unfortunate that you cannot provide full VIN numbers or any factory literature to support your case. I have, and I stand by it.
*based on engine production figures for 1969 provided by PHS, less T/A RA III production figures posted on transamworld.com.
FYI, RA III production figures vary widely from source to source and most are based on Fred Simmond's breakdown of engine production figures, rather than from PHS physical invoices, and therefore do not have the ability to take into account the presence/absence of 611.
