Image Credit: Mecum.Plum Crazy paint, a 440 Six Pack, and a TorqueFlite automatic would already make this 1970 Dodge Challenger R/T an interesting survivor. The lettering running down its flanks reveals that this particular Challenger has a considerably more colorful history than its specification sheet alone suggests.This wasn't simply a muscle car occasionally taken to the drag strip on weekends. It competed in American Hot Rod Association Showroom Stock racing and earned a quarter-mile world record at California's Fremont Drag Strip.Mecum now offers the Challenger at its Nashville 2026 auction as part of the Steve Meadows MSM Global Collection. It crosses the block on Friday, September 25, with time slips, ownership history, a broadcast sheet, warranty card, and other documentation accompanying the car.AdvertisementAdvertisementIts odometer currently shows only 16,934 miles, although Mecum carefully notes that this figure represents the mileage displayed rather than independently guaranteeing total mileage. Receipts documenting the car's mileage are also included in the sale.The 440 Six Pack Was Built For Serious PerformanceImage Credit: Mecum.This is a genuine V-code Challenger R/T equipped with Dodge's 440-cubic-inch Six Pack V8. The setup used three two-barrel carburetors and offered a formidable alternative to the considerably more famous 426 Hemi.Backing the 440 is a TorqueFlite automatic transmission, while a deep transmission pan and B&M shifter reflect the car's drag-racing past. Power front disc brakes were also fitted, giving the Challenger some additional stopping ability after a trip down the quarter-mile.Production figures suggest only 1,640 Challenger R/Ts received the 440 Six Pack for 1970. Of those, just 793 were reportedly equipped with the automatic transmission, putting this car into an already desirable configuration before its racing history is considered.It Became An AHRA World Record HolderImage Credit: Mecum.Mecum identifies the Challenger as an AHRA Showroom Stock quarter-mile world record holder at Fremont Drag Strip in California. Its surviving racing graphics reference its record-setting career, preserving a visual connection to the period when the car was actively competing.AdvertisementAdvertisementThe car is known as "Mother's Mo-Par II" and was driven by Patricia Werner. It is credited with a best quarter-mile performance of 12.43 seconds at 110.29 mph and held an AHRA Showroom B Stock world record during the early 1970s.Showroom Stock competition means that rather than becoming a radically altered drag car, the Challenger had to compete within rules intended to keep participating vehicles relatively close to their production configurations, making those figures particularly impressive.Its Racing History Is Still VisibleImage Credit: Mecum.The exterior is finished in its original Plum Crazy color and carries vintage-style racing lettering, including the driver's name, car name, sponsorship, and AHRA record information. Dual hood scoops and hood pins add to an appearance that wouldn't look out of place waiting in the staging lanes decades ago.Inside, it's very much what you'd expect to find in a 1970 Challenger. Black vinyl bucket seats, a center console, a wood-rimmed steering wheel, and a Chrysler Solid State pushbutton radio share the cabin with an AutoMeter Sport-Comp tachometer and the B&M shifter associated with its competition history.AdvertisementAdvertisementDocumentation accompanying a historic race car can be nearly as interesting as the hardware itself, and Mecum says the sale includes original time slips, an E-Bodies Build Sheet Vehicle Report, receipts, ownership history, and documentation related to the car's mileage.The Record-Holding Challenger Is Going Back To AuctionThis isn't the first time the Challenger has appeared at Mecum. It sold for a $60,000 hammer price at Mecum's Indianapolis auction in 2021, when the odometer showed 16,918 miles.Five years later, the display reads 16,934 miles, meaning only 16 additional miles have been added to the odometer since that sale. Mecum hasn't provided an estimate for what the Challenger might bring when bidding begins in Nashville.There are plenty of surviving 1970 Challengers with desirable engines and attention-grabbing colors, but not many come with a factory V-code 440 Six Pack, documented period racing history, and an AHRA quarter-mile world record attached to their name.AdvertisementAdvertisementIf you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
