69 T/8 M.T. Ram Air-III or H.O.
further done
All V/8 400 exc, Ram Air or H.O.
then
69 F/8-T/8 Ram Air-III, IV or H.O.
F=Firebird T=Tempest (GTO)
8=V8
I also remember 69 GTO's coming through our dealership without Ram Air but having H.O.
This was on the paperwork from GM, unfortunately some one took that from my possession years ago.
The above GM published catalog should do it on the matter? Also note I had already posted this catalog page in this thread, the answers were before you all along.
