Chrysler’s E-body platform gave birth to some of the most notorious muscle cars ever to roam the earth, with these two professionally restored 1970 pilot cars—one a Plymouth Cuda Convertible and the other a Dodge Challenger R/T Convertible—being among those first E-bodies that would launch the automobile manufacturer into a new decade. Sporting serial numbers 4 and 21, respectively, each car is powered by a V-code 440 Six Pack V-8 engine mated to a 4-speed manual transmission. These two stunning machines were both built on August 1, 1969, and hold the distinction of being the earliest known examples of convertible 440 Six Pack Cudas and Challengers ever built.

Dodge’s brand-new Challenger was an exciting introduction for 1970, and the Dodge Hamtramck plant in Detroit began building the new E-body models in late summer 1969. During the course of getting things underway for full-scale mass-assembly, vehicles are often test-built to make adjustments for that process. Constructed on Saturday, August 1, 1969, Serial No. 100021 is one of the very first Challengers ever created and is commonly believed to be the first 440 Six Pack Challenger Convertible built. In fact, according to research done when this spectacular car was documented for restoration, only three earlier 1970 Hamtramck Dodge VINs were known to exist.


The Challenger was the last of the so-called pony cars to emerge after the 1964 introduction of the Mustang gave rise to the breed. However, the R/T designation would last just two years, retiring from the product line at the end of 1971 along with the 440 Six Pack engine itself. Furthermore, convertible R/T models would only be built in 1970; there were none offered in ‘71. This car is likely the first of just 61 examples ever built by Dodge that received Six Pack power.

The Six Pack engine was just six months old at the time this car was built; prior to 1970 releases, it had only been available in a run of special Super Bees in the spring of 1969. These engines made use of the three Holley 2-barrel carburetors, as well as some internal component upgrades. Easier to keep in tune than the 426 Hemi, many buyers found the package extremely adequate in all driving situations.

This car is a stunning example regardless of its production date. Painted FE5
Bright Red with a color-matched white top, premium white vinyl interior and white longitudinal striping, it is a stellar example at first glance. That impression continues with the option list. Behind the matching-numbers 440 Six Pack engine went the A33 Track Pak to put the A833 4-speed, bullet-proof 3.54 Dana 60 Sure Grip differential and performance cooling-system upgrades onto this car. It also received a power convertible top, power steering, power front disc brakes and chrome 5-spoke wheels with Goodyear Polyglas tires.


The interior matches its driveline appeal: a six-way driver’s-side bucket seat, premium vinyl upholstery, wood-grain-type center console, Hurst Pistol Grip shifter, power windows, A01 light group, matched driver’s-side and passenger-side chromed mirrors, tinted glass, AM/FM stereo and a Rallye dash with tachometer. Beyond the superb FE5 Bright Red paint (coded specifically on the fender tag as Y91—Show Car finish) are hood pins, chrome tips, a luggage rack, performance hood, 440 Six Pack callouts, R/T-notated stripe and a flip-open gas-filler cap.

Presented today as it left the factory, this car was refreshed to outstanding condition by Restorations by Julius in Chatsworth, California. Included with the Challenger are the Chrysler Registry report, a copy of the May 1970 “Dodge News Magazine,” a copy of the December 1969 “Car Life” magazine featuring a Six Pack convertible road test, and restoration invoices and photos.
