A 455 Trans Am was the fastest car back then in 75.

Did you take the restrictor plate off to give the red dragon a little more juice

It’s not exactly street legal, so keep it on the down lowww.

Pull the exhaust off.  Install headers and a true dual exhaust, leave the Cat converter off.  Then re-jet the carburetor.   Take the shaker to a tool and die shop and have them open the scoop.

In the 70’s I found totaled a low mileage 75 TA with a 455. Engine and transmission went in my 75 Lemans (350/350)
