How much horsepower does a 1972 Demon have?
In factory terms, a 1972 Demon powered by the 340-cubic-inch V8 was rated at 275 horsepower gross. In modern terms, the figure would be lower, typically around 180–230 horsepower depending on exhaust configuration and measurement standards.
Context and history
The Demon badge was Mopar's performance label used on certain high‑performance A‑body cars in the early 1970s, notably the Plymouth Duster and related models. For the 1972 Demon, the best-known configuration was the 340 cubic‑inch V8 with a 4‑barrel carburetor, designed to deliver strong acceleration for its size and price class.
Core specifications
Here are the key specifications commonly cited for the 1972 Demon’s powertrain. All horsepower figures refer to factory gross horsepower as rated at the crank in 1972.
- Engine: 340 cubic-inch V8
- Configuration: 4-barrel carburetor
- Factory horsepower (gross): 275 hp
- Subject drivetrain: typically paired with manual or automatic transmissions of the era
These figures define the baseline for the 1972 Demon as sold by Mopar in that year, with slight variations possible by production batch and market.
Understanding the rating in context
Gross horsepower ratings from the era do not include modern testing conditions or aftermarket components. They measure engine output with all accessories removed, which inflated the number compared with today’s net ratings. When people refer to the Demon’s performance in everyday terms, they are often speaking about the car’s real-world output with the full car, which is typically lower than the factory gross figure.
Net horsepower implications
In practical terms, net horsepower for a 1972 Demon would usually fall in the approximate range of 180–230 hp, depending on exhaust, carburetion, emissions equipment, and drivetrain configuration. This range is approximate because exact numbers varied by emission controls, tuning, and vehicle condition over time.
Summary
The 1972 Demon’s official power rating was 275 horsepower gross from the 340‑CID V8, reflecting the horsepower measurement standards of its time. When comparing to modern figures, expect a lower net output due to aging components and the difference between gross and net rating. The Demon remains a standout example of Mopar’s early-1970s performance ethos.
