New Member 1971 Pontiac Grand Prix SJ 455


Hello Folks, 

New to the Forum, just wanted to post a few picks of of my ride. Wonder how many of these are still around? 

 

1971 Grand Prix SJ model  48,400 original miles. Highly Optioned - see build sheet

 Bought last year from owner since 1973.

 Lots of paperwork, Protecto-plate, new owner warranty card, 2 factory build sheets

 GM of Canada Documented

 Frame off restoration 2007-2008.

 New suspension, new master flow exhaust with ceramic headers.

 New rims and tires

 Has the original 455 engine 325hp / differential with an upgraded 200 4R O/D trans allows 70 mph @ 2100 rpm. 3:55 Gears from 3:07

Factory AM/FM stereo with 8 Track between the bucket seats

 

1971 was first year for many new Grand Prix options, that this SJ has:

-New boat tail design

-Custom painted sport side mirrors, 

-Premium automatic climate-controlled air conditioning 

-Radio antenna in windshield

-Heated electric rear window defog

-Honeycomb sport wheels in storage

 

Formal, classic, loaded, and luxurious, this 1971 Pontiac Grand Prix has true classic car distinction. So, check out all the details, from the big numbers-matching V8 under the hood to the comfy A/C interior, and youll soon understand what 1970s personal luxury was all about. This car understands how to maximize its appeal. 

The factory-correct silver paint has a nice luster that loves to highlight the long-pointed hood, sharp creases in the fenders, and the artful lines of the trunk. Theres no better way to show off a hardtop profile than with a black vinyl roof, and theres even a full-length black pinstripe to match. The full package has a very well-integrated look where this was one of the final years before new bumper laws took effect, and so these chrome kings know how to hug the body lines. 

From day one this Pontiac has elegance. GM even gave this the Model SJ designation that was borrowed from Duesenberg as part of a way to show these were premium machines. The details really justify this. This Grand Prix has a timeless grand style everywhere from the flush-fitting pop-out door handles, to the way the headlights gracefully rise above the front sheet metal. We love it when the roof color is also a preview of the interior color. Personal luxury means high-back seats finished with a button-top design, and a front fold-down armrest gives bucket-like individuality up front. Plus, the dash wraps around you. Your gauges are set deep into a three-pod design like a European sports car, and its an easy reach to nice features like the cold-blowing factory air conditioning. 

This is a well-preserved true classic. So, youll really appreciate the time capsule details, like the working AM/FM radio with a separate 8-track player. Under the hood is Pontiacs legendary 455 cubic-inch V8, and this is the cars numbers-matching motor and rear axle. Its topped with a four-barrel carburetor because they knew how to make sure this coupe could move with confidence. Its a well-respected package, and that makes it a great classic for the road. Features like the 4 speed 200-R4 overdrive transmission, power steering, and power brakes w/discs up front continue this easy cruiser feeling. A Grand Prix is all about a great luxury classic, and this one has the looks, features, power, and poise to live up to. 

Thanks for Looking!

The Gentleman's GTO, nothing Sleeper about this. I loved driving my Aunt's SJ when I was in my twenties, pretty much untouchable on the street. 

The Silver with Vinyl top is classic.

Hey thanks guys,

Found a little more info on the 1971 GP story as quoted from a Motor Trend write up below. Seems 4884 units were produced but would be interesting to know the paint Color breakdowns for that year.

 Grand Prix received some significant design changes for 1971. The most notable included single headlights that replaced the previous dual-style treatment, a new decklid with pronounced boat-tail styling, and new bumpers front and rear. Interior changes were limited, but the same overall theme was retained. It seemed as if excitement about the Grand Prix was peaking. Enthusiasm regarding what was underhood was another story, however.

General Motors imposed a compression-ratio restriction on all divisions for 1971. By limiting the ratio to a maximum of 8.5:1, engines could operate on lower-octane unleaded fuels, ultimately reducing tailpipe emissions. However, the reduction negatively affected engine output. If that weren't enough, a new method of net rating output-which more closely represented actual engine output when installed in a vehicle with all accessories connected and operating in normal underhood conditions-made it seem as if the '71 engines were mere shadows of their former selves.

The 400 four-barrel remained the standard powerplant in the Grand Prix Model J, but its new 8.2:1 compression ratio caused its gross horsepower rating to slip to 300. Its net rating was 255 hp-or what appeared to be nearly 100 less than the 1970 offering. As in previous years, the three-speed manual transmission was standard, while the four-speed manual and Turbo 400 remained extra cost options. Rated at 325 gross and 260 net horsepower, the 455 four-barrel was no longer available with a manual transmission. And the 400 two-barrel was cancelled.

 

For 1971, the SJ package retailed for $195 and again included such items as the 455 four-barrel engine, Rally gauges, custom lamp group, and specific SJ identification. There were, however, a few new features in the package such as vinyl accent stripes, body-colored sport mirrors, and the Delco X battery-a high-tech unit that was completely sealed and required no periodic maintenance while offering higher power reserves.

As promising as 1971 looked for the Grand Prix, the UAW launched a massive strike on September 14, 1970, that halted vehicle production at every GM assembly plant across the country-including the three that built Grand Prixs. Sixty-seven days later, the strike was officially resolved, but it took some plants several weeks after that to resume production. The Grand Prix's Lakewood, Georgia, plant, for one, sat idle until January 29, 1971, greatly affecting availability.

 

Once production was back in full force, a running change to standard equipment was made midyear. Sales Information Bulletin 71-16 was issued on April 23, 1971, announcing the cancellation of the manual transmission on several models including the Grand Prix. It stated the Turbo 400 would become the only transmission available on vehicles in the affected model lines shipped on or after May 1. It went on to add that base prices would be changed accordingly.

Production records indicate that just 116 manual transmissions had been installed into Grand Prixs up to that point (64 400 three-speeds and 52 400 four-speeds), so sluggish sales may be partially responsible for the midyear cancellation. But the 67-day strike and resumption delays caused total production to dip to just 58,325 units for the model year. The Model J represented 53,441 of those, while 4,884 SJs were produced. Another 2,365 455 four-barrel engines were installed in Grand Prix Js.

 

  My Dad had a new decked out 77 SJ with power sunroof, was the first car I ever drove at 10yrs old (on a gravel backroads). 
Always loved the Buick, Olds, Beaumont and Pontiac classics.., Surprised they never gained more recognition or command higher prices today (68-72), but that may change. Seems everyone has a Camaro, Mustang, etc.

Not knocking those at all, just saying that as history goes on one would think the obscurity of the rare BOP classics should gain even more interest.

 

An all time favourite for myself would be a 67 triple black Beaumont 4 speed 396 SD.. Kick myself in the ass as had passed up on the opportunity years ago.

 

Thanks and cheers!

Nice car with the perfect color scheme for that model!

A quick technical correction, automatic climate-controlled air conditioning, Radio antenna in windshield and Heated electric rear window defog had been offered since 1969. The SJ package was tweaked in 71 as you mentioned with some features added and the auto level system dropped from the package.

Gorgeous car!
