Truck

Hey guys, I'm scouring the internet here and I have a question about old Shelby's. In 1968, they produced 7 Trans Am Coupes with the 440 HP 302. Apparently, it had a high-rise intake, and oversized exhaust, but how else could I identify it?

To be fair, I'm asking about my '69 Mustang which has somethings I can't explain. For one, it has finned valve covers (in the old style.) I just read about this Shelby Deal, and I'm trying to make the ends meet.
