Watch: Honoring the Legend of the Pontiac Trans Am Super Duty with 1,000 HP by Sebastien Bell February 26, 2018 Share Comments For those of us who weren’t around for this, it’s stunning to look back at how quickly the muscle car era died. For example, sales of the Firebird dropped more than 56% between 1971 and 1972. So, by the time the Trans Am Super Duty rolled off the line in ’73, the fun was done. With a 455 ci engine (a $521 option), making 290 hp (less than the promised 310 hp, thanks to the EPA), a four speed manual, and 3.42 gears (for the non-A/C cars), the car was a weapon, but one deeply behind the times. So, in a way, there was no better time to bring the Trans Am Super Duty back. The Trans Am Depot Super Duty comes years after the death of Pontiac, but it does at least come at a time when stupid-big horsepower figures are acceptable. And stupid-big these horsepower figures are. Making more than 1,000 hp and 1,000 lb-ft of torque on 91 octane fuel, according to the makers, the Super Duty makes the most of its name. It’s more than just a name, though. Trans Am Depot wanted to do more than just change a bit of fascia, so it took a 375 ci block, and changed just about everything until it displaced 455 cubic inches. According to the guys who made it, though, they weren’t looking to make a racecar. Despite the gobs of carbon fiber and the enormous power-output, they wanted it to be as liveable as possible. To accomplish that, they got help from NASCAR legend Joey Arrington to make sure that not only would the engine be powerful, but reliable, too. And to make sure it looked right, they got in touch with a Swedish designer called Bo Zolland, who has worked with people like Jay Leno to make wild cars a reality. You can watch the much more cinematic telling of the story with a new video from Trans Am Depot, above.
