Story

1961 Chrysler 300G

The 1961 300G was the seventh Chrysler 300 letter car and the last with the towering fins that had defined the series since 1956. Its inverted grille and canted paired headlamps gave the front a new identity, while the hardtop and convertible retained the four-seat, high-performance grand-touring formula.

Two bodies, one letter car

Chrysler offered style 842 as a pillarless two-door hardtop and style 845 as a convertible, both on a 126-inch wheelbase. Published club records report 1,280 hardtops and 337 convertibles, for 1,617 cars. Body, top, structure, weight, price, restoration details, and market observations remain configuration-specific.

Cross-Ram power

The standard 413-cubic-inch wedge used hydraulic lifters and two Carter AFB 2903S four-barrels on ram manifolds. Chrysler rated it at 375 gross horsepower and 495 lb-ft. An optional mechanical-lifter, short-runner configuration produced 400 gross horsepower and 465 lb-ft at a higher engine speed. Red manifolds and dual carburetors alone do not establish which engine a car was built with.

TorqueFlite, manual, and axle choices

Most 300Gs used the push-button A-466 TorqueFlite. A heavy-duty Chrysler three-speed manual was available by special order, but not with air conditioning. The standard rear-axle ratio changed to 3.23 for 1961; 3.15, 3.58, and 3.73 ratios and Sure-Grip were available by configuration. Cases, controls, gearing, tags, dates, and records must agree.

Chassis, brakes, paint, and cabin

The unit body used torsion-bar independent front suspension and a seven-leaf-spring live rear axle. Power-assisted 12-inch drums were standard at all four wheels. Four factory colors were documented: Formal Black, Mardi Gras Red, Cinnamon, and Alaskan White. Inside were four tan-leather bucket seats, swivel front seats, a full console, and the AstraDome instrument cluster.

Authentication boundaries

Identity starts with the 8413 serial pattern, style 842 or 845 body data, and RP41 engine assembly identification, then expands to the whole car. Ram hardware, transmission, clutch controls, axle, suspension, brakes, paint, trim, upholstery, instruments, and ownership records should reconcile. Club survey evidence indicates that deck-lid 300 numerals appeared during production, but it does not support a hard serial cutoff.

Price and market context

The hardtop listed for $4,952 and the convertible for $5,352 before delivery and options. Dated guide and auction records span different bodies, conditions, equipment, and restorations. They show historical market context rather than a current appraisal or proof of another car's configuration.

Still Researching

  • production The reviewed sources establish hardtop, convertible, and total production but not a final audited split for 375-hp versus 400-hp engines or automatic versus manual transmissions.
  • authenticity markers Club survey evidence indicates an early-to-late deck-lid numeral change but does not establish a hard serial-number cutoff, and no model-level source proves an individual car's original drivetrain, paint, trim, or equipment.
