Congratulations to all who have contributed. We now have 379 images! But I'd like to shoot for at least 400 images - equalling the number of cubic inches of the GP's standard engine of this period, and then maybe 428 (the big '69 engine) and possibly 455 (big engine for '70-72) and then some!

Group DescriptionThis group is devoted to photos and other images related to the 1969-72 Pontiac Grand Prix, which was described as "the modern classic" in its day and the first of the intermediate-sized personal luxury cars that would take Detroit by storm in the 1970s. In addition to photos of cars, images such as GP advertisements of this era are welcome along with images of original brochures and even magazine road tests.
These cars featured chiseled styling with the longest hood of any automobile in history - six feet of it, and squared off bodylines. Inside was an aircraft-inspired interior with Strato bucket seats facing a wrap-around cockpit style instrument panel that put all controls and instruments within easy reach of the driver. Separating the bucket seats was a center console with floor shifter slanted toward the driver that swept into the instrument panel. These cars also featured a number of automotive advances such as a new nickel-plated rear window defroster, hidden radio antenna in the windshield and pop-open exterior door handles.
First year for the G-body Grand Prix which was based on the Pontiac Tempest/LeMans A-body intermediates. Wheebase was 118 inches and overall length was 210 inches, as a result of a six-foot long hood - the longest in the industry.
Engine offerings this year included a standard 350-horsepower 400 cubic-inch V8 with four-barrel carburetor and dual exhausts on the Model J, with a regular-fuel 265-horsepower 400 from the full-sized Pontiacs offered as a no-cost economy option with automatic transmission. Standard engine on the Model SJ and optional on the J was a 370-horsepower 428 cubic-inch V8 and a higher-output 390 horsepower 428 HO engine was optional on both models.
Standard transmission was a three-speed manual with Hurst floor shifter. Options included close- and wide-ratio four-speed manuals with Hurst shifters or the three-speed Turbo Hydra-matic with console-mounted shifter that would permit both automatic and manual shifting that was also available in that year's GTO, Firebird and LeMans models.
Other standard equipment on the 1969 Grand Prix included Strato bucket seats in expanded vinyl or cloth-and-vinyl trim, center console, custom cushioned steering wheel, custom wheel covers, electric clock and nylon loop blend carpeting on floor and lower door panels. The SJ option added the 428 V8 along with Automatic Level Control suspension, light group, power front disc brakes, redline or whitewall "Wide Oval tires and SJ badges.
Extra cost options on '69 GPs included variable ratio power steering, AM or AM-FM stereo radio with antenna concealed in windshield, air conditioning, power windows and driver's seat, leather upholstery (which also included luxurious cut-pile carpeting and door courtesy lights, Rally II wheels and heated rear window defroster.
Only minor changes including GRAND PRIX nameplates moved from lower front fenders to B-pillar and chrome louvers from B-pillar to lower front fenders. Grille now featured vertical bars and tailight lenses were revised with chrome surroundings.
Power front disc brakes now standard on all models and upholstery trim patterns revised for both standard vinyl or cloth/vinyl and optional leather upholstery, along with door panels featuring revised door handles and new "GP" logos. Notchback bench seat with armrest officially became no-cost option this year after a few late '69 models were so equipped and included a dashboard glove box and column mounted shifter for automatic transmission not found on cars with Strato bucket seats and console.
350-horsepower 400 remained standard engine on Model J with 265-horsepower regular-fuel 400 a no-cost option. Replacing the two 428 V8s offered in 1969 was a new 370-horsepower 455 cubic-inch V8 standard on Model SJ and optional on J.
Grand Prixs now came with side impact protection in the form of rails in the doors and rear-quarter panels that were introduced on the 1969 full-sized Pontiacs and other GM big cars.
New vertical bar grille and separate bumper grille assembly flanked by new single headlights replacing the duals of previous years up front and a revised "boat-tail" like rear section. Engines reduced to 400 4-bbl (300 horsepower) standard on Model J and 455 4-bbl (325 horsepower) standard on SJ and optional on J - both engines feature lowered compression ratios to permit use of lower octane regular leaded or unleaded gasoline.
Power steering now standard on all models and Turbo Hydra-matic included with the SJ option. Three-speed manual transmission initially standard on Model J with 400 engine and four-speed manual was optional along with Turbo Hydra-matic. At mid-year the automatic became standard on both models and manual transmissions were dropped.
Inside, revised interior trims feature new patterns for both expanded Morrokide vinyl or cloth and Morrokide upholstery for both Strato bucket seats and no-cost notchback bench seat. The leather seat option was discontinued.
New option this year was GM's Delco X sealed battery that never needed water standard on SJ and optional on Model J.
New crosshatch grille inserts and revised triple cluster tailight lenses were the most noticeable apperance changes on the 1972 Grand Prix. The 400 and 455 engines were carried over from 1971 but with lower "on paper" horsepower ratings to 250 and 300, thanks mostly to the switch from gross horsepower figures based on dynometer without accessories to the Society of Automotive Engineers new "net" measurements based upon an engine as installed in a vehicle with accessories and emission controls hooked up.
Inside, cloth/Morrokide upholstery was carried over with expanded Morrokide now being perforated for easier breathing on both Strato bucket seats and notchback bench seats. The burled-elm trim of previous years was replaced by a new simulated teakwood design. Early models had 140 MPH speedometers of previous years but at mid year were scaled back to 120 MPH to make room for new "FASTEN SEAT BELTS" light.
A few '72 GPs built later in the model year were equipped with radial tires introduced as a mid-year option. These tires were supplied by GM's regular tire suppliers including Firestone, B.F. Goodrich and Uniroyal.
