This is not my car but...
This COOL picture taken by my mother in apx April, 1971 in Anaconda, Montana.
The '68 Firebird in the picture would have only been 3 years old at the time. BUT... the most interesting thing about this car... notice how it's a 400 Firebird AND has the H.O. stripe. I understand the H.O. stripe could be ordered as an option, and to my knowledge, the 400 H.O. never came with the stripe (the stripe was for the 350 H.O.). I have never seen another 400 car that originally had this, have you?
