1980 Pontiac Grand Prix: The Final SJ Year by the Compiled Tables

This record's own dek describes 1980 as the final SJ year by the compiled tables, with 7,087 SJ built. This record's own overview states that MuscleCarClub, crediting the Standard Catalog of Pontiac, gives 1980 Grand Prix production as 114,714, split between a base "J" hardtop at 72,659, an "LJ" hardtop at 34,968, and an "SJ" hardtop at 7,087, and that the compiled engine tables list a 231 cid V6 at 110 hp and 190 lb-ft, a 265 cid V8 at 120 hp and 210 lb-ft, two 301 cid V8s at 140 hp/240 lb-ft and 155 hp/240 lb-ft, and a Chevrolet 305 cid V8 at 150 hp and 230 lb-ft, all SAE net as compiled with no rpm given.¹

This record's own keyFacts section states that Pontiac's 1980 brochure lists automatic transmission with every Grand Prix engine, the Buick 231 V-6 code LD5, the Pontiac 265 V-8 code LS5, the 301 four-barrel code L37 (with electronic spark control code W72 on the SJ), and the Chevrolet 305 four-barrel code LG4 for California; it also gives factory prices of $6,219 for the V-6 Grand Prix or $6,399 for the V-8, $6,598 or $6,778 for the LJ, and $7,296 for the SJ. This record's own prices section carries all five of these same factory prices by trim and drivetrain.²

This record's own engines section carries all five entries matching the overview and keyFacts, adding availability detail: the LD5 V-6 base on Grand Prix and LJ, the LS5 available on Grand Prix and LJ, the L37 available on Grand Prix and LJ, the electronically controlled L37-with-W72 base on the SJ at 155 hp, and the LG4 base on the SJ and available on Grand Prix and LJ in California. This record's own conflicts section flags a dispute over the 305's own carburetion: the compiled engine table lists it as a two-barrel at 150 hp and 230 lb-ft, while the 1980 full-line brochure lists the same LG4 code as a four-barrel, California only, with this record's own treatment note favoring the brochure and suggesting the compiled table's two-barrel entry may belong to another model. This record's own transmissions section lists a single entry, Automatic, standard with every engine, column shift or floor shift with bucket seats.¹

This record's own production section carries four rows, the 72,659-unit J, the 34,968-unit LJ, the 7,087-unit SJ, and the 114,714 total, with a note that the source presents the base, LJ and SJ 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 options section itemizes two-tone and double two-tone paint, a digital quartz clock, cruise control, a remote deck lid release, an electric rear window defroster, rally gauges with instrument-panel tachometer, Soft Ray tinted glass, a removable hatch roof, tungsten quartz halogen headlamps, cornering lamps, a power antenna, power door locks, driver's seat and windows, AM/FM stereo in several formats up to a 40-channel CB, a reclining passenger seat, a tilt steering wheel, power glass or metal sunroofs, a medium trailer group, controlled-cycle windshield wipers, 205/70R14 white-letter tires with the Rally Handling Package (not offered on the LJ), and Rally II, body-color Rally II, cast aluminum or genuine wire wheels, alongside the SJ's and LJ's own equipment content by name.¹

This record's own interiors section carries five entries: the standard Grand Prix notchback seat in new cloth and vinyl or all-vinyl with simulated Regal walnut trim and cut-pile carpeting; the LJ's own luxury loose-pillow seats in new Florentine cloth; the SJ's own specific vinyl front bucket seats with console; Viscount leather-with-vinyl bucket seats available on the LJ and SJ; and the seven recommended interior colors named on the 1980 color chart, Oyster, Black, Blue, Green, Camel Tan, Carmine and Maroon.

This record's own specifications section gives shipping weights of 3,139/3,263 pounds V-6/V-8 for the Grand Prix, 3,279/3,406 pounds V-6/V-8 for the LJ, and 3,291 pounds for the SJ, along with a 201.4-inch overall length, 72.7-inch overall width, 108.1-inch wheelbase, front/rear tread of 58.5/57.8 inches, front/rear head room of 37.6/37.8 inches, front/rear leg room of 42.8/36.3 inches, front/rear shoulder room of 56.4/55.9 inches, front/rear hip room of 51.7/54.9 inches, 16.1 cubic feet of trunk capacity, an 18.1-US-gallon fuel tank, 195/75R14 standard tires with a compact spare, and axle ratios that this record's own text lists separately for each engine and trim.²

This record's own performance section is empty for the year, leaving no period road test on record for the 1980 Grand Prix. This record's own identification section gives series 2G, body style J37 for the Grand Prix, K37 for the LJ, and H37 for the SJ, and separately describes the 1980 paint chart's own two-digit body color codes with U and L suffixes for two-tone combinations.²
