Rich,

The 1973 Trans Am cars had the 'gaudy' Front Spoiler, and Front and Rear front-flared Wheel Wells, besides that 'funky' Bird hood decal.

The Formula 455 and Formula SD-455 cars had the cleaner looking front valance {fiberglass} with a small air-dam spoiler, all as one-piece.

As seen in the photo {Post #28}.

On all the EGR and Smog connections,,,,,,,,,, my father pulled all that stuff off, and disconnected the Air Conditioning Pump, and
removed it., replaced the Cast-Iron Intake with an Edelbrock Spead-Bore Intake, and played around with the 800 CFM Rochester carburetor..

Once the SD-455 Engine got warm, it was like somebody filled the gas tank with 'Jet Fuel'..........
