The screaming chicken got its name from the bird that is on
the hood of the Trans Ams. Each color of car had a special
black bird with flames that matched: Cameo White cars had a
bird with blue flames, Brewster Green had green flames and
the Buccaneer Red cars had a red/orange flames.
The weird thing about the "screaming chicken" is that it's
not a chicken at all, but rather it's a "firebird!" It does
look like it's screaming (you would be too if you were going
up in flames) though.
The Famous Trans Am Shaker Scoop
The "shaker scoop" was the name given to the 'reverse bug
catcher' that stuck out of the middle of the hood. The
reason it is a "shaker" scoop is because it shakes with the
engine. Every time you goose the engine, she rocks left to
right like it's going to tear the engine mounts right off.
If you had a real Super Duty engine, the shaker scoop had
the SD-455 emblems.
In some of the early birds, the shaker scoop was a
functional air intake source. It was vacuum operated with a
solenoid that would open the rear flap under hard
acceleration to allow more air in. 73 marked the first year
the solenoid was removed and the flap was screwed on. Let's
face, it just looked cool but didn't add any real
performance.
What Color Is Your Bird?
If you wanted a 73 TA, you could have it in any color as
long as it was Cameo White, Brewster Green or Buccaneer Red.
For me, green was a bit dull and the red had too much orange
in it.
The Cameo White car, Blue Firebird on the hood and Black
interior was by far the best color combination for 1973.
