Was that what it was classed circa '69, or more recently? SS/JA seems rather far down the line for being the same body style as the SS/F GTX, and only a relatively small amount diff in HP and/or weight. Even in the few short years from say '68-'71, I see cars that were reclassed quite a few times, so that's why I was wondering if anyone knows what the '68 Roadrunners(383) were classed when they were new.
