This 1972 Dodge Demon is a comprehensively built restomod, taking one of Mopar’s most charismatic compact muscle cars and adding serious stroker-V8 muscle and modern hardware. Its 340ci V8 has been enlarged to 416 cubic inches and topped with a triple-carburetor Six Pack setup, backed by upgraded brakes, suspension, and cooling. Finished in black over black vinyl with a matching vinyl roof, it is a well-executed, driver-focused build of a rising collectible, and it is offered on Bring a Trailer.

What it’s worth right now
The Demon 340 is a rising, affordable corner of the classic Mopar market. Classic.com data puts the 1971-1972 Demon 340 average around $44,875, with Hagerty valuing good examples near $35,000 and mint cars climbing toward $75,000, and values have been rising sharply, up roughly 17 percent year-over-year for good cars. This is a modified stroker build rather than a stock 340, so it is valued on the quality of the build and its driver appeal rather than on originality.

Given the desirable and rising Demon platform and the quality of the stroker build but accounting for its modified, non-original nature, the repaint, and the disclosed history, I would call fair value roughly $28,000 to $45,000. The current $16,000 bid with two bids and six days remaining is below that and should climb as the auction develops, with the final figure reflecting how the market rewards the build against its driver-grade details.
Condition and details
The build is thorough and performance-focused. The original 340 was stroked to 416 cubic inches in 2004 with triple Holley carburetors, an Edelbrock intake and Performer RPM heads, Doug’s headers, and a Be Cool radiator with dual fans, producing 485 horsepower and 521 lb-ft on a 2004 dyno. It drives through a rebuilt TorqueFlite 727 automatic and a limited-slip differential with Moser axles, rides on QA1 control arms and staggered American Racing wheels, and stops with Wilwood four-wheel discs, with Classic Auto Air climate control added during the refurbishment.

For condition, the car was refurbished in a process concluding in 2019, having been repainted black from its factory Dark Green Metallic after the driver-side quarter panel was replaced due to old accident damage and rust repair was performed. The digital odometer shows 2,600 miles said to reflect distance since the refurbishment, though true mileage is unknown, and the car comes with a broadcast sheet, decoded fender tag, and records. Disclosed flaws are a cracked passenger-side dash pad, an erratic fuel gauge, and carburetors that lack a choke.

The diligence on a stroker restomod is about build quality and honesty. The comments praised this as a high-standard build with the right components, but a buyer should still have the engine, the triple-carb setup, and the driveline inspected, since execution is everything on a modified car. Understand the digital odometer is not true mileage and confirm the broadcast sheet and fender tag against the car. This is a private-party sale with a clean North Carolina title.

What makes the Demon unique
The Dodge Demon holds a special, slightly mischievous place in Mopar muscle-car lore. Introduced for 1971 as Dodge’s version of the Plymouth Duster, a compact, lightweight A-body, it earned enthusiast affection for its wicked stance, its evil “Demon” badging complete with a little pitchfork-wielding devil, and the surprising performance that its low weight extracted from the 340ci small-block V8. By 1972, with the Charger and Challenger increasingly tamed by tightening regulations, the Demon 340 was arguably the most genuinely exciting and affordable Mopar you could buy, a proper baby hot rod from the factory.
Bring a Trailer
Today that combination of light weight, cheeky character, and rising collectibility has made the Demon 340 one of the best values in classic American muscle, and an ideal platform for exactly the kind of build seen here. Stroking the 340 to 416 cubic inches with a Six Pack induction transforms the car’s performance while retaining its charismatic looks, and the modern brakes, suspension, and air conditioning make it genuinely usable. For a buyer who wants a distinctive, potent, and comparatively affordable Mopar that stands apart from the ubiquitous Camaros and Mustangs, a well-built Demon like this delivers real character and muscle.
My take
This is a comprehensively built, genuinely potent Demon restomod, pairing one of the most charismatic and rapidly appreciating compact Mopars with a stroked 416 Six Pack and modern brakes, suspension, and cooling. My fair-value call is $28,000 to $45,000, reflecting the desirable, rising Demon platform and the quality of the stroker build against its modified nature, the repaint, and the disclosed accident-repaired quarter panel and unknown true mileage, so before treating the current $16,000 bid as the entry point a buyer should have the engine and driveline inspected, verify the documentation against the car, and value it as the well-executed driver it is.
