1970 Dodge Challenger T/A

1970 Dodge Challenger T/A

The Dodge Challenger made its debut in the fall of 1969 as a 1970 model. While it shared Chrysler’s “E-body” short-deck, long-hood platform with the third-generation Plymouth Barracuda, Dodge Challenger’s wheelbase was two inches longer, creating more interior space.

The Dodge Challenger was originally offered as either a two-door hardtop or convertible, in base, SE (Special Edition), R/T (Road/Track) and T/A (Trans Am) trim. But it was the range of powertrain choices that was truly remarkable.

Befitting the brand’s performance heritage, the Dodge Challenger went racing in its first year. For the street, it was offered in the limited-edition T/A model to meet homologation requirements for Sports Car Club of America (SCCA) Trans Am racing. The T/A was one of the first production vehicles to offer different size tires, front and back; E60 x 15 in the front, G60 x 15 in the rear.

In 1970, Sam Posey drove the lone Trans Am racing Challenger, prepared and run by Ray Caldwell’s Autodynamics Race Shop. While he didn’t win a race in the No. 77 car, Posey finished fourth overall in points.

The interior is period-corr

ect in presentation, with white vinyl upholstery and door panels that are offset by a black dash, a black floor console, and a three-spoke steering wheel with a wood-grained rim. The Challenger also features a steering column-mounted tachometer, a “pistol-grip” Hurst shifter, and power brakes. Underhood resides the strong 340 cubic inch V8 engine with “Six Pack” induction, which, like the Boss 302 and Z28 engines, was severely underrated at 290 horsepower.
