1970 Dodge Challenger

A 1970-only model was the Dodge Challenger T/A (Trans Am) racing homologation car. In order to race in the Sports Car Club of America's Trans American Sedan Championship, it built a street version of its race car (just like Plymouth with its Plymouth 'Cuda AAR) which it called the Dodge Challenger T/A (Trans Am). Although the race cars ran a destroked version of the 340, street versions took the 340 and added a trio of two-barrel carburetors atop an Edelbrock aluminum intake manifold, creating the 340 Six Pack. Dodge rated the 340 Six Pack at 290 bhp (216.3 kW), only 15 bhp (11 kW) more than the original 340 engine (and mysteriously the same rating as the Camaro Z/28 and Ford Boss 302 Mustang), it actually made about 320 bhp (238.6 kW).

It breathed air through a suitcase sized air scoop molded into the pinned down, hinged matte-black fiberglass hood. Low-restriction dual exhausts ran to the stock muffler location under the trunk, then reversed direction to exit in chrome tipped "megaphone" outlets in front of the rear wheels. Options included a TorqueFlite automatic or pistol-grip Hurst-shifted four-speed transmission, 3.55:1 or 3.90:1 gears, as well as manual or power steering. Front disc brakes were standard. The special Rallye suspension used heavy duty parts and increased the camber of the rear springs. The T/A was among the first production vehicles to use different size tires front and rear: E60x15 fronts, and G60x15 in back.

The modified camber elevated the tail enough to clear the rear rubber and its side exhaust outlets, thick side stripes, bold ID graphics, a fiberglass ducktail rear spoiler, as well as a fiberglass front spoiler added to the image. The interior was strictly stock Challenger. Unfortunately, the race Challenger T/A was not competitive, due to the fact that they had to be large enough to accommodate engines as large as the 426 Hemi, and 440, the street version suffered from severe understeer in fast corners. It could turn mid 14s in the quarter mile, which would do any small block muscle car proud. The T/A would only be available for 1970 as Dodge pulled out of Trans Am racing. Only 2,142 T/As were made.
