Early production 400 HO 69 Firebirds use the Ram Air name for the 400HO option, they realized the confusion and changed it to 400HO on the invoice during the model year (there is a bulletin about it).
The confusion stems from the fact that on the 69 GTO the 400HO option included the Ram Air system (and was therefore called Ram Air 400) but on the Firebird the Ram Air set up was a separate option offered only if you also ordered the 400 HO.
Lastly, the Ram Air hood inlet option was only released mid year so this car in question is built much too early to have had that option.
