Nothing on the trim tag will tell you it's a Firebird 400. All the "telltale signs" of the Firebird 400 option can be recreated now using repro parts, so PHS is the only way to know for sure. Just be forewarned, most of the 1969 Firebird 400's you see today are phony. They made around 11,500 Firebird 400's in 1969 (compared to 65,000 1969 GTO's), and you don't see too many 69 GTO's around! By comparison, they made around 11,000 Judges between 1969-1971 Judges, so a real 1969 Firebird 400 is tough to find.
The Firebird 400 option was an entire package, much the same way the 64-65 GTO option was over a Lemans, so PHS is the only way to know for sure.
Unique to the 400 models :
Chrome trim surrounding each grille.
Pontiac crest at the leading edge of the front bumper.
Dual scooped hood (also came on the 350 H.O.)
Filler panels between the radiator support and the front bumper to help cooling.
400 emblems on the hood scoops and right rear corner of trunk lid.
All Firebird 400 models, with auto trans, used the Turbo 400.
All Firebird 400 models used dual exhaust.
All Firebird 400 models had 4-barrel carbs (some GTO's were built with 2-barrels).
Lower baffle pan between core support and front valence (a/c cars had this too)
Chrome valve covers and air cleaner lid (Firebird 400's used the GTO engine)
14x7 wheels were standard.
HD alternator
HD starter
HD radiator
Just a footnote, ALL 69 Firebirds used a 160 mph speedo.
Hope that helps...
