Our previous attempts at chronicling NASCAR history and Petty racecars have been pretty shoddy — so please see the full Mecum Auctions writeup below the AMAZING photo set here. Fast facts are:
— this is believed to be the only 1973 Petty-built racecar still surviving
— entered circuit for the ’74 season, and was raced until the late 1980s
— original driver? None other than Dale Earnhardt
The most shocking detail? The price estimate of $40k to $80k!
Another semi interesting tidbit? There seems to be a possible ‘special mode’ — or something — right above the gauge bezels. Some slight scratches in the polished alloy around a mounting hole indicate a paper-clip inserted here might unlock some kind of super beast mode? Or not. But full of rich presence and charisma regardless.

1973 Dodge Challenger Race Car
Petty Enterprises Built Kit Car
ESTIMATE: $40,000 – $80,000
In the early-1970s, Chrysler came up with a unique program to help promote its vehicles in sportsman-level circle-track racing. These were racecars in kit form, released through their then-distributor Petty Enterprises and developed by the legendary Larry Rathgeb, who was also part of the streamlined Charger Daytona and Plymouth Superbird programs. The new kit allowed performance-minded buyers to buy all of the pre-fitted hardware as needed to fabricate a race-legal vehicle, and they eventually could be purchased through Mopar dealers nationwide. The car seen here is one of the prototypes built for the testing program used to develop appoximately 30 customer cars that were later sold during Chrysler’s kit car program, and has been restored to its 1973 configuration. Moreover, this is believed to be the sole surviving example to surface to date. Starting with the basic Petty Enterprises chassis, the car could be bodied as a Chrysler A- or E-model. Details are important in any race restoration, and this one features a real W2-head, roller-cam 355 CI small-block Chrysler engine, complete with proper Holley 4-barrel carburetor with LeMans-type float bowls and M/T valve covers. A 4-speed transmission and an original Petty Enterprises full-floating Chrysler 8.75 differential make up the driveline. The car retained the rare chromed slot-type race wheels with correct Petty Enterprises center caps. Exterior décor includes race lettering, period-type sponsor identification, engine callouts, scoop-type hood, two-piece deck spoiler, rear window tie-down straps, and headlamp/tail lamp block-off plates. Inside are period correct gauges to monitor engine functions, a Hurst shifter, roll cage, and single seat; the car still retains its 4-piston Hurst-Airheart front disc brakes. Upgrades for the modern era include braided lines with AN-fittings, cooling system upgrades, and an ATL fuel cell. This rare Chrysler E-body racecar was featured on “My Classic Car” with host Dennis Gage and the Hot Rod Network.
