1970 Pontiac Grand Prix

The 1970 Pontiac Grand Prix was basically a carryover from the previous year except the grille itself now featured vertical slats, and vertical hash marks appeared on the front fenders just behind the front wheels. New interior upholstery patterns and the reintroduction of the bench seat rounded out the visual changes.

The big change in the 1970 Pontiac Grand Prix was a new engine. The 428 disappeared, its robust spot taken up by the new 455 V8, apparently the largest engine ever put inside a Grand Prix. It hit 370-hp and 500 lb-ft of torque. The four hundred V8s stayed the same, at either 265-hp with the 2-barrel carb or 350-hp with the 4-barrel. In addition to the J and SJ trims, a restricted number of custom-built Hurst SSJ Grand Prix were sold in 1970. These were J models shipped out to Hurst, who installed an electric sunroof, Hurst shifter, gold Rally II wheels, and special body-colored sport mirrors.

Outside, vertical slats replaced horizontal ones in the grille and the nameplate was moved to the side rear of the car. Also new on 1970 Pontiac Grand Prix was a special Hurst SSJ version, a semi-custom conversion with electric sunroof, gold-colored wheels, and Hurst shifter. The SSJ started life as J models (the vinyl accent stripes on SJs were incompatible ) built by Pontiac, than sent to Hurst. All 272 vehicles were painted either Cameo white (code CC) or Starlight Black (code AA). Interiors were ivory, black, or sandlewood in material or all-Morrokide.

Mandatory options included body-color Sport mirrors, G78 x fourteen whitewalls and Rally II wheels. The Space-Saver spare and Ride & Handling package were advocated. After assembly, the automobiles were distributed to a Hurst plant in Southfield, Michigan where Frost Gold accents were applied to the hood, side windows, front of the roof, and Rally II wheels. A landau-style half-top ( Antique white, white, or black) was installed, as was a steel electronically operated sunroof (similar to that used in the Cadillac Eldorado.

Interior

1970 Pontiac Grand Prix Interior

The 1970 Pontiac Grand Prix was basically a carryover from the massively successful 1969 edition. Only a couple of points differed. The grille itself now featured vertical slats, and vertical hash marks appeared on the front fenders just behind the front wheels. New interior upholstery patterns and the reintroduction of the bench seat rounded out the visual changes.

Also new in the 1970 Pontiac Grand Prix were standard power front brakes. The bench seat returned as an option, but as part but as part of a package that forced you to get automated transmission and a steering wheel-mounted shifter. While bucket seat models featured the shifter and glove box in the middle floor console, the glove box in bench models was now in the dashboard.
