Of those 7,500 Tenth Anniversary Editions, only 1,817 had the L78 6.6L 400ci V8 and the Borg Warner T-10 4-speed. Today this silver Screamin Chicken sits a true survivor with only 5,674 miles registering on its odometer. You would never guess that this Firebird is nearly 40 years old. The body looks absolutely stunning and is covered in the original two-tone paint. At the front of the body is a special massive screaming chicken decal that rests on the hood. Above the decal is the shaker hood that has the lettering T/A 6.6 on either side. On the roof you will find correct, mirrored T-tops. At the back of the car is a slick rear spoiler and more Trans Am badging. Pop the hood on this Firebird and youll be greeted by an original L78 6.6L 400ci V8. Due to emission standards, 1979 was the final year that Pontiac offered all of its larger displacement engines. Bolted to the 400 cubic inch Pontiac V8 is the original 4-speed Borg Warner Super T-10 transmission, which sends power to a 3.23 Posi-traction rear end.
