1973 Trans Am Exhaust SD455

1973 Super Duty Trans Am Exhaust, open hood scoop, Gardner Exhaust, SD455, idling

Here is an excerpt from Popular Hot Rodding Magazine (September 1982) full page write-up about the 73-74 Super Duty Trans Am.
The first and last paragraphs:

"Probably one of the most awesome engines ever produced by Pontiac was the Super Duty which was built in two versions, 1961-1963 and 1973-1974. The Super Duty engine was ahead of its time churning out great doses of torque and horsepower. When combined with the Trans Am body style it made for an unbeatable combination of power and handling.




.......




All Super Duty Trans Ams came with the 8 1/2-inch 10-bolt rear end, and with the optional 3.42 to 1 rear gearing were capable of running 13.90-second quarter mile times. If you're interested in picking up a Super Duty T/A today, they run between $5,000 and $10,000 depending on condition. If you can't afford one, pretend you can and take a test ride. Once you've been in one, you won't forget what they look, sound, and feel like."

was this car restored at Second Generation ?

@dbrm125

The paint (acrylic lacquer) was done before I got the car by Auto Image of Ventura, CA. (May 88)

Interior was done around the same time near Ventura also.

Motor, front end, suspension, etc. were rebuilt 2007-08 near Braselton, GA

Where is Second Generation located btw?

I heard somewhere that the SD455's were found to produce a fair amount more than 310 BHP, I heard it was closer to about 370?

@DarkAngel2504

correct, it was "detuned" to meet emissions for 1973.

This motor, rebuilt to complete stock specs dynoed at 376 hp. (8.4 to 1 factory compression was advertised)

The SD455's respond extremely well to upgrades: cam, higher compression and headers get you over 500 hp very easily.
