1983 Pontiac Grand Prix: The 305 Tops the Gasoline Engines

This record's own dek states that the J, LJ and Brougham continue for 1983, with the 305 four-barrel the top gasoline V8. This record's own overview states that MuscleCarClub, crediting the Standard Catalog of Pontiac, gives 1983 Grand Prix production as 85,798, split between a base "J" hardtop at 41,511, an "LJ" hardtop at 33,785, and a Brougham hardtop at 10,502, and that the compiled engine tables list a 231 cid V6 at 110 hp and 190 lb-ft, a 350 cid V8 diesel at 105 hp and 205 lb-ft, and a Chevrolet 305 cid V8 at 150 hp and 240 lb-ft, all SAE net as compiled with no rpm given.¹

This record's own keyFacts section states that Pontiac's 1983 brochure lists three Grand Prix engines, all with automatic transmission, the Buick 3.8 V-6 code LD5 standard, the Chevrolet 5.0 four-barrel V-8 code LG4, and the Oldsmobile 5.7 diesel V-8 code LF9; it also gives factory prices of $8,698 for the V-6 Grand Prix or $8,923 for the V-8, $9,166 or $9,391 for the LJ, and $9,781 or $10,006 for the Brougham. This record's own prices section carries all six of these same factory prices by trim and drivetrain.²

This record's own engines section carries the matching three entries: the LD5 standard federal and California, the LF9 diesel optional and requiring air conditioning, Oldsmobile-built, and the LG4 four-barrel optional, Chevrolet-built, the top gasoline V8 this record's own dek names. This record's own transmissions section lists a single entry, Automatic, the only gearbox this record's own engines section pairs with any of the three powerplants.¹

This record's own production section carries four rows, the 41,511-unit J, the 33,785-unit LJ, the 10,502-unit Brougham, and the 85,798 total, with a note that the source presents the base, LJ and Brougham rows as summing to the total, and a second note stating plainly that no engine, transmission, paint or trim counts were found. This record's own paint section is empty for the year. This record's own options section itemizes a Brougham Landau option by its own full content, luxury acoustics, Tampico carpeting, pedal trim plates, a lamp group, door courtesy lamps, a padded landau vinyl top with rear window insert, opera lamps, rear quarter courtesy lamps and chrome bumper guards, restricted to the Brougham; air conditioning, required with the diesel; a Rally cluster and trip odometer, with tachometer not offered with the diesel; a removable glass-panel hatch roof; sport mirrors with left remote and optional right remote convex; a Delco-GM AM radio; bucket seats with recliners and console, not offered on the Brougham; a tilt steering wheel requiring the luxury cushion wheel; a power glass sunroof with manual sliding sunshade; a padded landau top; cast aluminum wheels, Rally II wheels with trim rings, and wire wheel covers with a locking package; a 60/40 notchback front seat standard on the Brougham; and power windows standard on the Brougham.¹

This record's own specifications section is sparse for the year, carrying only a single entry, 195/75R14 steel-belted radial blackwall standard tires across the Grand Prix, LJ and Brougham.

This record's own performance and conflicts sections are both empty for the year, leaving no period road test and no disputed figure on record for the 1983 Grand Prix. This record's own identification section gives series 2G, body style J37 for the Grand Prix, K37 for the LJ, and P37 for the Brougham, sourced to the same Standard Catalog tables as this record's own production and price rows.²
