Since Norwood was a GM plant with a separate Fisher body plant attached to it in 69, I would have to raise the BS flag. If the owner to be was a GM employee, he certainly wasn't allowed on the Fisher side of the plant, and vis versa, that was practically a firing offence back in the day. So if you beleive the stories you could either get extra body options installed if you worked for Fisher (did they get discounts?), or extra drive train options installed if you worked for GM, but not both. The 427 would not have benn "assembled" at Norwood, it came from Tonawanda, just like every other big block stuck in a Camaro since January of 67, so the owner would not have "built" the engine either, at best he bolted it up to the tranny and stuck some accesories on it before it went into the car. Maybe he stuck a temperature gauge into the intake manifold, but since the original manifold didn't have a spare place to "stick" it I would think that that is unlikely as well. You might have better luck at getting some extras if you worked at a GMAD plant. Once the car left the line, who knows what could have been done to these cars, I guess it just comes down to who you knew at the time.

If its not on the build sheets, window sticker or shipping paperwork it might have left the factory with it, but lets see someone prove it. I've heard the stories about plant that would put anything you wanted into the car if you paid for it (my local Framingham MA plant comes to mind), but I've never actually seen one or heard about one locally that ever had that done.
