Trans Am Shaker Assemblies

Here are a few pictures of Trans Am Shaker assemblies

The 1977 T/A shaker is a low rise shaker, they do not come above the hood very far.

In 1978 they made the scoop taller.

Here is a picture and dimensions of the 1979 air cleaner sent to me by Bill Boyle.

Note the size of the "snout",  the 1978/1979 220 HP motors have a larger snout than the 185 HP motor.

This is the air cleaner in my 1978 T/A.

The bottom view of my 1978 T/A hood scoop.

This is a 1976 bird using a Performer intake and Performer 750 cfm Carb.

A 1/2" spacer was used to regain lost height. Thanks to Kevin for this picture
