Well, I stopped looking because it's obvious they're not Mopar, and they look awful on the car. I suspect they may be late-model Pontiac, but it doesn't matter. They're scrap.
Pontiac hasn't made a cool hood scoop since the '79 Z-code Shaker (meaning the engine was a Pontiac 400 with a 4-speed). Prior to that, it was the '76 Formula, as the '77-up Formula hoods looked like King Kong stepped on them. much like the "6.6 Litre" Trans Am Shakers (all 403 Olds, all automatic) which rode too low and looked like ass compared to the "T/A 6.6" cars. The scoop on the Olds-motored cars barely clears the hood... and yes, it's a different scoop than the 400 Poncho cars.
