This record's own dek states that 1984 brought Base, LE and Brougham trims, with the Chevrolet 305 as the V8. This record's own overview states that MuscleCarClub, crediting the Standard Catalog of Pontiac, gives 1984 Grand Prix production as 77,444, split between a base hardtop at 36,893, an "LE" hardtop at 31,037, and a Brougham hardtop at 9,514, 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 prices section carries all six of these same factory prices by trim and drivetrain.²

This record's own identification section gives series 2G, body style J37 for the Grand Prix, K37 for the LE, and P37 for the Brougham, sourced to the same Standard Catalog tables as this record's own production and price rows.²
