Renamed, and Triple-Confirmed by Count Alone
Renamed Dart Sport, the fastback's 340 model sold 11,315 in the 340's final year.
United States · researched through 2026-09-23
For 1973 Dodge renamed the Demon the Dart Sport, and the 340-powered version, Dart Sport 340, is put at 11,315 units by two separately named compilations, the Govier/Consumer Guide 340 table and MuscleCarClub; the same 340 table describes 1973 as the 340 engine's last production year in the Dart Sport. Flory's reference book independently confirms the identical 11,315 figure under style number LM29, a third source agreeing exactly rather than merely rounding to a nearby number, so all three sources consulted for the year converge on the same count.1,2,3
Flory separately gives 68,113 for the base Dart Sport under style LL29, and his own table prints a percentage-change figure alongside each row, +30.06% for the 340 and +70.79% for the base car, though the source does not state explicitly which prior period those percentages are measured against; this record carries the two production counts themselves without restating those percentage columns as independently confirmed facts. Summing Flory's two rows yields 79,428, a total this record computes itself and marks as estimated, since Flory lists the two body styles separately rather than printing a combined line of his own. Because both the 340 and the base-engine rows come from the same table and the same edition, this computed 79,428 total rests entirely on Flory's own tabulated numbers rather than combining figures drawn from two disagreeing lineages.3
Base manufacturer's suggested retail price ran $2,853 for the Dart Sport 340 against $2,424 for the base Dart Sport, a $429 gap, and shipping weight for the 340 is recorded at 3,205 lb; all three figures come from the same single Flory table that also supplies the two production counts above. No transmission split of the 11,315 total was found in the sources consulted, and no total-Dart-Sport figure spanning every body style was captured from a named source either, so the 79,428 combined figure in this record's production section is this record's own arithmetic rather than a number either compilation prints directly.3
Beyond production, pricing, and that one shipping weight, no engine ratings, transmission choices, options, paint colors, interior trim, performance figures, or identification codes for 1973 survive in the sources consulted. The engine, transmissions, options, paint, interiors, performance, and identification sections of this record are accordingly left empty rather than populated with figures carried over by assumption from the 340's known displacement and general reputation. One further source specifically covering 1973 Dart Sport 340 ratings, equipment, and prices was found but not read directly in this pass; this record's gaps for 1973 reflect that unread source rather than a documented absence of the underlying facts.2
The 340's status as its own last production year, stated by the production-figures compilation rather than by Flory or MuscleCarClub, is carried here as that one source's own characterization rather than independently confirmed by a factory announcement or a second reference work; no source consulted explains what replaced the 340 in the Dart Sport lineup for the following year or why 1973 marked that engine's end specifically. This record therefore states the claim with its single-source attribution intact, rather than restating it as an uncontested fact about the wider Dart Sport engine lineup beyond what that one compilation actually says.1

Every figure is labeled with how sure we are. Reported means a manufacturer, registry, or reference figure we cite but have not reconciled against factory records ourselves. Disputed means credible sources disagree and both are shown. Rows are separately scoped; don't add them together unless the note says they make up a total.

No total Dart Sport or transmission split was captured from a named source.
Flory lists the Dart Sport (LL29) and Dart Sport 340 (LM29) as separate styles for 1973.
The 79,428 total row is computed from this record's own two Flory-sourced rows (status kept as 'estimated').
