y'all are correct... those "chevelle"s are basically a Hopped up Camaro w/ a body kit ( a little more involved, but basically...)
the Company, Trans Am worldwide(Formerly "Trans Am Depot"), Started with similarly turning camaros into "Trans Ams". not firebirds...
they even briefly (6 episodes) had a "reality" show on discovery called "Trans Am"

Post–Pontiac Trans Am
In 2012, General Motors signed a licensing deal with Trans Am Depot to use the Trans Am name and Pontiac logos in custom coach built versions of new Trans Am. Under this agreement, Trans Am Depot takes brand-new model
Chevrolet Camaros, strips them down to their basic components and rebuilds what looks like a new Trans Am. They make these in the designs of the 6T9 version Trans Am, 6T9 Goat ("GTO"), 7T7 Trans Am and the limited-edition Hurst Trans Am.
On March 26, 2017, at the
New York International Auto Show, the Bandit Edition Trans Am was introduced. Built by Trans Am Depot, only 77 will be produced, each signed by
Burt Reynolds. Powertrain is a 455 cu in (7.5 L)
direct injection version of the current Generation V
LT1 V8 engine equipped with a 2.3 litres (140.4 cu in) Magnuson
supercharger with a boost of 14 psi (0.97 bar), developing 1,000 hp (746 kW) and 1,046 lb⋅ft (1,418 N⋅m) of torque.
