What Is The 1971 Dodge Demon 340?
Built on the compact Dodge Dart A-body platform, the 1971 Dodge Demon 340 blended small-block performance with lightweight handling, wrapped in an aggressive and rebellious design. Released during the final golden era of American muscle cars, the Demon stood out for its potent 340 cubic-inch V8, playful design cues, and a unique spirit that continues to resonate with Mopar enthusiasts.
1. Small-Block Muscle: The Power Beneath The Hood
At the heart of the Demon 340 roared a 340-cubic-inch V8 engine rated at 275 horsepower and 340 lb-ft of torque. Featuring a four-barrel carburetor and 10.3:1 compression, it delivered big performance in a lightweight package. Drivers could choose from a standard three-speed manual, an optional four-speed manual, or the TorqueFlite automatic transmission (Source: Hemmings).
2. Heavy-Duty Suspension: Superior Handling For Its Era
Unlike many traditional muscle cars known for straight-line speed but sloppy handling, the Demon 340 came factory-equipped with serious suspension upgrades: larger torsion bars, a beefier front anti-roll bar, six-leaf rear springs, and heavy-duty shocks. These enhancements allowed sharper cornering and a more connected driving experience compared to heavier contemporaries (Source: Dodge Archives).
3. Gimmicks With Character: Eye-Catching Design Touches
The 1971 Dodge Demon’s bold character was visible through its mischievous cartoon Demon mascot, unique graphics, and exclusive interior trim. Dodge’s edgy marketing was designed to appeal to a younger, rebellious audience—and today, these playful elements have become highly collectible.
4. Lighter Curb Weight: A Critical Performance Advantage
Weighing around 3,340 pounds, the Demon 340 was significantly lighter than heavyweight muscle machines like the Charger R/T. Its reduced mass meant quicker acceleration, better handling, and stronger braking—all critical factors that gave it an edge on the street and track (Source: Hagerty).
5. Rarity Adds Value: A Hidden Gem For Collectors
Only 10,098 units of the 1971 Dodge Demon 340 were built, making it relatively rare compared to mass-produced muscle cars of the era. This scarcity increases its appeal to collectors who seek authentic Mopar classics that remain accessible in price.
6. Striking Styling: A Fastback That Commands Attention
Offered exclusively as a fastback coupe, the Demon 340 featured aggressive body lines, wide stance, and sporty proportions that set it apart from the more subdued Dart Swinger. Its styling captured Dodge’s philosophy of bold, youthful design at the time (Source: Hemmings).
7. 1971: The Pinnacle Year Before The Muscle Car Decline
The 1971 model year was a sweet spot for muscle car enthusiasts. Emissions regulations and insurance crackdowns that came later would cripple performance numbers. The Demon’s 10.3:1 compression ratio and robust output represent one of the last high-compression factory V8s before the decline of the golden era.
8. Carrying The Legacy: Dodge Demon In Modern Performance Culture
The spirit of the original Demon was revived in 2017 with the Challenger SRT Demon, a supercharged drag-strip monster capable of 0–60 mph in a mind-blowing 2.3 seconds. The 2023 Challenger SRT Demon 170 carried this legacy forward, linking the rebellious 1971 Demon 340 to Dodge’s modern dominance in performance (Source: Dodge Official).
9. Performance Metrics: Punching Above Its Weight
Contemporary road tests showed the Demon 340 sprinting from 0–60 mph in just 6.5 seconds and running the quarter-mile in 14.49 seconds—figures that rivaled and sometimes beat heavier big-block competitors (Source: Motor Trend Archives).
10. Affordability: A Smart Entry Into The Classic Muscle Market
In today’s collector market, clean examples of the 1971 Dodge Demon 340 typically range between $20,000 to $35,000 (Source: Hagerty Valuation). This affordability makes it an attractive entry point for enthusiasts seeking authentic muscle without the steep prices commanded by more famous Mopars.
