Trans Am’s Nightmare in Sublime Green, 1970 Dodge Challenger T/A

In 1970, Dodge needed a street warrior that could legitimize their Trans Am racing ambitions. The result was the Challenger T/A, a one-year-only homologation special that took everything wild about the base Challenger and cranked it to eleven. With its aggressive aerodynamics, side-exit exhausts, and that unmistakable flat-black fiberglass hood, the T/A was built for battle both on track and boulevard.

Racing Pedigree Meets Street Attitude

The Challenger T/A existed for one simple reason: SCCA Trans Am racing rules required manufacturers to build at least 2,500 street versions to qualify for competition. While Plymouth had their ‘Cuda AAR, Dodge crafted their own interpretation with the T/A package, creating what many consider the most visually aggressive E-body ever produced.

Under that functional fiberglass hood lived a 340 cubic inch V8 equipped with three two-barrel carburetors, the famous “Six Pack” setup typically reserved for big-block engines. This combination produced a conservative factory rating of 290 horsepower, though real-world output was likely much higher. The engine’s lumpy cam created an unmistakable idle that announced the car’s intentions from blocks away.

Form Follows Function

Every visual element of the T/A served a purpose. The rear ducktail spoiler wasn’t just for show, it helped plant the rear end at speed. The side-exit exhaust pipes, emerging just ahead of the rear wheels, created one of the most distinctive exhaust notes in muscle car history while reducing back pressure. The front and rear spoilers, along with the racing stripes, were all standard equipment.

Most T/As came painted in high-impact colors like Sublime Green, Plum Crazy Purple, or In-Violet, with flat-black hoods and rear spoilers creating a menacing contrast. The look was purposeful and aggressive, a street machine that clearly meant business.

The Driving Experience

Behind the wheel, the T/A delivered on its visual promises. The 340 Six Pack engine provided tremendous torque throughout the rev range, with a power delivery that was both smooth and savage. The side pipes created an intoxicating soundtrack, especially under hard acceleration when all six barrels opened up.

The suspension was tuned for performance, with heavy-duty components that sacrificed some comfort for improved handling. The Rallye wheels, wrapped in Goodyear Polyglas GT tires, provided decent grip for the era, though the T/A was always more about straight-line performance than cornering finesse.

Short-Lived Glory

Production ended after just one model year, with only 2,399 units built. Changes in racing rules and emissions regulations meant the T/A concept wouldn’t survive into 1971. This brevity has only enhanced the car’s legend, making it one of the most sought-after E-body variants today.

The Challenger T/A represents everything that made the original muscle car era special: uncompromising performance, distinctive style, and an attitude that couldn’t be tamed by committee or regulation. Built for just one glorious year, it remains the ultimate expression of Dodge’s racing ambitions in street form. Today, finding a clean T/A requires serious money, but you’re buying a piece of automotive rebellion that will never be replicated.
