1964 Pontiac Grand Prix: A Carryover Year Topped by the 421 HO
A carryover year: 63,810 built, with the 370 hp 421 HO at the top of the option list.
United States · researched through 2026-09-23
This record's own dek describes 1964 as a carryover year: 63,810 built, with the 370-hp 421 HO at the top of the option list. This record's own overview states that the Grand Prix kept the 303-hp four-barrel 389 as standard and added dual exhausts and foam cushions to its Bonneville-level equipment, with the compiled table recording 63,810 built at $3,499.1,2
This record's own engines section carries two ratings for the standard 389 four-barrel depending on transmission: 303 hp at 4,600 rpm and 430 lb-ft with automatic, or 306 hp at 4,800 rpm and 420 lb-ft with manual. Above that, this record's own engines section lists an all-lines optional 389 Tri-Power at 330 hp and 430 lb-ft, a 421 four-barrel at 320 hp and 455 lb-ft, a 421 Tri-Power at 350 hp and 455 lb-ft, and the 421 HO Tri-Power at 370 hp and 460 lb-ft, the same top engine this record's own dek names.1
This record's own transmissions section lists a heavy-duty three-speed manual standard at 2.49/1.59/1.00, an optional four-speed manual built by Muncie in wide-ratio M-20 or close-ratio M-21 form that this record's own text notes replaced the Borg-Warner T-10, geared 2.54/1.92/1.50/1.00 for the 389 and 2.20/1.64/1.30/1.00 for the 421, and an optional three-speed Hydra-Matic at 2.93/1.56/1.00. This record's own options section, again a full-size line list without item-by-item Grand Prix marking, itemizes air conditioning at $430, aluminum hubs and drums from $122 to $138, a Cordova top at $86, an instrument gauge cluster from $21 to $59, power brakes at $57, a power seat at $96, a power tilt bucket seat (left-hand) at $71, a remote control mirror at $12, sports wheel covers from $30 to $46, and a tachometer at $54.1
This record's own paint table lists fifteen colors by code and name beginning with Starlight Black and Cameo Ivory, each sourced to the same fact sheet's Body Paint Color Codes listing with no per-color production published. This record's own interiors section carries a single entry: Morrokide upholstery, bucket seats, the center console, and foam cushions, the same cushion upgrade this record's own overview already names.1
This record's own specifications section gives a 120.0-inch wheelbase, 213.0-inch overall length, 54.6-inch overall height, and a 3,930-pound shipping weight for the Grand Prix. It also carries full-size Pontiac figures not specific to the Grand Prix: a 79.2-inch overall width, 64.0-inch rear track, and 8.00 x 14 standard tires, all cross-sourced between the Over-Drive fact sheet and the factory AMA sheet issued September 6, 1963; the AMA sheet alone gives standard axle ratios of 3.23:1 with manual and 3.08:1 with automatic in its own Grand Prix column. This record's own conflicts section notes a front-track dispute for the full-size line, 62.5 inches in the fact sheet against 63 inches in the AMA sheet, with the AMA sheet treated as primary.1,2,3
This record's own performance section is empty for the year, leaving no period road test on record for the 1964 Grand Prix; the dek's own 370-hp 421 HO figure and the engines section's own ratings are this record's only performance-adjacent data for the model year. This record's own identification section gives only series 29, body 2957, sourced to the same production compilation as the model-year total, and this record's own keyFacts section restates the 63,810 production total as its sole entry for the year, cross-sourced to both the production compilation and MuscleCarClub.com's own first-generation production figures.2,4

Coverage: Partial — researched sections are shown; missing ones are not yet sourced. Researched through 2026-09-23.
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.
