2 of my 68 firebirds 

both of my firebird were sprints which means the 4 bbl engine, 10 1/2 compression, and split exhaust manifold-so , yes, they had the performance option

I've had 2 1968 firebird sprints in my life. One when i got back from Vietnam and ordered it new, and one in 2005 . The green one was a 3 speed, custom interior, ralley gauge pac , optional wood grain steering wheel, fold down rear seat, and rear mounted antenna. The red one was a 4 speed, tilt wheel, custom interior, hood tach, rallyII wheels, and console. The green one i did a few changes over the years and after a guy keyed the whole car i repainted it myself.
