The Rare Muscle Car That The World Forgot - The 1973 Pontiac GTO

[@rich1891]

38 year GM Pontiac mechanic here, I outlasted Pontiac by one year. Retired now. 🇺🇸

[@johnhutchison9782]

Yes, but Pontiac beat you to retirement😂 thanks for your service to the General. You are a true mechanic, not some air breather that has to plug an electrical device into the car to figure out what's wrong with it.

[@johnharris6655]

My dad sold Pontiacs back in the 60's. When the first GTO hit the show room floor he talked his boss into letting him take one to the local drag strip to show it off. My dad was a professional part time racer so the boss trusted him. He said he was being custom drag racers in a GTO with a 389 and Hurst Shifter with the window stickers still on it. Talk about win on Sunday Sell on Monday. He said Monday morning there were guys from the track waiting out side for the dealership to open an one bough the car he took to the track and it was still dirty.

[@draxicous906]

That's a cool story man!

[@ralphvalkenhoff2887]

Great story, share some pictures.

[@DavidWendorf-pk8mj]

In 1976 I was in the USMC and stationed in San Diego. A friend who had acquired a '65 GTO with blueprinted 389 and 4 speed Hurst shifter as payment for totaling his Ford Pinto with it, sold it to me for $400 (friend also got his insurance payout so had no need for the GOAT). It was red and I replaced the destroyed passenger front fender with a yellow one from a junk yard. The only other change I made to it was a pair of M50s on the back. I raced from stop light to stop light with everything I could find in San Diego for a year, including many '67 GTOs (which were much more popular at the time) and never came close to losing - only using 2nd and 3rd gears. It wouldn't break those M50s loose but got awesome wheelies in 2nd gear. The starter went out soon after I got it, so push started it everywhere and learned to park on hills when possible. PFCs didn't make much money in those days so took a couple months to save for the starter. It had the folding front end, which eventually led to it's doom. When putting it on a lift to fix the starter, the front end fell apart (probably from a combination of the accident with the Pinto and my wheelies). I searched all over California for parts but couldn't find any. Eventually left it on the side of a road in San Diego. Still kicking myself for not finding a way to transport it home (Wisconsin) for future repairs. I've had a lot of muscle cars since then that would have easily run it down in 1/4 mile, but none faster from stop light to stop light. :)

they had planned on doing that, but pontiac got into some serious trouble for putting a thermal switch to turn all the emissions equipment off after the car heated up on all their v8s causing them to need to revise their intake manifold design and retrofit all of their current inventory. It just added too much of a delay to production and the 455sd gto never made it to the customers that had ordered it.

[@hendo337]

The car to have in '73 was the Grand Am 4 door 400 4 speed. That was a real thing, the grandfather of the G8 GXP 6M and Chevrolet SS 6M cars that are so sought after today.

[@drippinglass]

Why would you want 4 doors?

[@automotivehistorian]

The 1973 Grand Am design was suppose to be the GTO. At the time, the Pontiac Product Planners wanted a performance 4-door sedan to compete with the European 4-door Mercedes and BMWs that we’re starting to gain popularity in the US, however the decision to put the GTO nameplate onto a 4-door just didn’t seem to sit well with management so the Grand Am was born (utilizing Grand Prix/Trans Am name). The 4-door 4-speed 400 and Auto 455 Grand Ams were good looking and great handling cars and are sought after by Pontiac car collectors today.

[@louyork8379]

I actually know a guy that has a couple 73 Grand Ams. Both 2 drs but I remember when he got them back in 2000, I laughed cause it was such a lame car. He still has them today. They have increased considerably in value. Only smart thing ole boy ever did lol

I think there are actually quite a few examples of mid 70s cars which we didn't really appreciate back in the day because we were so disappointed in the decline in power but which turned out to be very nice vehicles. It's unfortunate that so few survived. If only we could've seen into the future and how much different our perspectives would've been all those years later.

No, not a Canadian only car. It was just the GTO that was available in 74, made out of a Ventura and came with only a Pontiac 350 engine. There was a Sprint in the 70's, but it was the GMC version of the El Camino, which of course was a cross between a Chevelle/Malibu and a pickup truck. Look up GMC Sprint. So, you must be thinking of something else. The Grand Am was made from 73-75, so maybe you're thinking of a 75 Grand Am, would be similar in body to the 73 GTO. There was also the limited production, one year only Can Am in 1977, also similar in body style. @@goldwingconepatterns2565

This was the time of 4 cylinder X cars, the Aries/Reliant, and 125 horsepower HT4100 V8s in a 4000 lb Sedan DeVille. People today scoff at 8 sec 0-60 times (what's a Honda Acord, 6.5?).

The 4 door Colonade cars had a newly added pillar between the front and rear side windows, while the 2 door version had the pillar as well as rear glass that was bonded in place. I don't imagine that last feature was much appreciated by rear passengers of un-air-conditioned cars, but it probably contributed to the structural integrity of the body, which was passed through the rubber mounts to the chassis, part of the reason the '73s were better handlers than the '72s.

In 74 you could get a grand am with a 455, and in 75 - 76 you could get the LeMans sport, and then 77 you could get the CAN AM.. Pontiac kept going making as much performance as they could over other gm a bodies

[@markothwriter]

I have a 1973 Pontiac LeMans Sport Coupe. It's almost the same as the GTO-- though not all GTOs are the same. The Sport Coupe does not have hood vents. Mine has the 400 L78 engine and a shifter on the floor. I think some GTOs with the same engine had a better carburator and better transmission. I really like it on the open road. very very smooth to drive. relaxing. I suppose I could look into removing the emissions devices - whatever those are.

[@grand73am]

The GTO came standard with the hood scoops, so it was sometimes called the GTO hood. But, the hood was optional on the Lemans Sport Coupe, if you really wanted one. The carburetor and transmission wasn't any better on a GTO than the LSC. They used the same engines and transmissions. Only difference was the GTO came standard with a 400, with the 455 optional. The LSC normally came with a 350, but 400 and 455 was optional. The main difference between them, other than the GTO decals, was that the GTO was setup for better handling with larger sway bars, 1-1/8" front and 1" rear. As for emissions devices, the only thing 73's had was an EGR valve on the intake manifold. 73 was the first year for that. It's the round tin can with a hex shape in the center, on the passenger side of the carburetor (not to be confused with the round choke housing on the carburetor). There should be a rubber vacuum hose connected to it. Disconnect the hose and put a plug in the hose, so you don't have a vacuum leak. You can cap the pipe on the EGR valve too, if you wish, but it's not necessary. The EGR is there to allow exhaust gas to enter into the fuel side of the intake, and basically pollute the fuel. So disconnecting the EGR allows better fuel and the engine will run better.

I do not know if the SD-455 was put in the car as a "special edition" or original. They did not have any 1973 SD-455 Firebirds on the lot and sold the only two they were able to get from Pontiac. I kept the Judge for a couple more years and bought a Dodge Van when the van craze took over in 1975. The good old days

I remember when the 73s came out. They were such a good looking car. For a while. The swept under side panels soon took the brunt of the stone chips, watr, mud, salt, and in a few years the sides had all rusted out.

[@youtubecarspottersguide1]

same with the grand am and 73 cutlas S ,best looking of the colande styles

[@grand73am]

I don't deny that happened to some of them. But I think it depends on where you lived and how it was cared for as to whether they rusted out. I have 3 73's and a 75 here in the Atlanta area, and none are rusted out. The 75 Lemans Sport spent 25 years with the original owner in N. Dakota and is still in great condition. He didn't drive it in the salt and kept it washed.

[@automotivehistorian]

The GTO was pretty much forgotten as a new car in 1973. This was the beginning of the personal luxury car craze (Monte Carlo, Regal, Cutlass Supreme) and European like 4-door performance sedans (Laguna and Cutlass Salon). The Pontiac Grand Prix and Grand Am overshadowed the GTO with much prettier styling. Further choking the GTO nameplate out of the market was the LeMans GT, which you could pretty much option like a GTO for less money.

[@slaytanic777]

Can definitely see what ended up turning into the Grand Prix/can am. Me personally would much rather have a can am. The 73 gto is a sad reminder that it's a end of the muscle car era.

[@davidbolt5113]

The Pontiac A-body Colonades were the best of the Colonades from GM. And 1973 was the best year. I’d take any.

[@tedlawrence4189]

Had a new '73 GTO when I was 24. Black 455. Only came with THM tranny. Mine had 342 posi rear,ps,pb and am radio. No air etc. 250 net hp. That is about 290-300 gross hp as pre 1971 engines were rated as. Kinda slow compared to earlier high perf. vehicles. Compared to other '73 hi-perf. cars it did quite well. Very few were around so I was often asked about it. It was based on the LeMans platform,while the last GTO of 1974,was based on the Nova platform! It came with a 350. It sold it in 1980. I then purchased a 14,000 mile '70 'Cuda from California. Also black. 440 6 pack,Torqueflite,373 posi,manual steering and brakes,no radio. Eagle GT tires. Equiped this way it was quick on the street. Very few,100 % stock non blown, cars were faster. The guys with the big block Ford's and Chevy's did not like my little Mopar.

Hope you still have the 'Cuda.

I had a 73 Bonneville .Green with white interior. That was a great car. I bet that GTO was too!

[@driverjamescopeland]

Buick had the best post-emissions 455. As a matter of fact, even though lower compression started in '71, only one year after being made publicly available... the revised oiling, front mount distributor, and lighter overall castings made the Buick a better engine.

[@stevedeleon8775]

[@CarsandCats]

I regularly attend car shows and I've NEVER seen a '73 GTO. They must be really rare.

[@1983jblack]

The GTO wasn't even a separate model anymore (That ended after 1971 and the GTO became an option again). GTO was more of an appearance package by 1973 much like the 442 was for the Cutlass. The original idea was for GTO to get the Grand-Am's interior/exterior/underpinnings, but Pontiac wanted to expand their market to combat the European cars and the GTO name wasn't capable of doing so

[@bewilderment9268]

I owned a '74 LeMans Sport Coupe with a 350 engine, buckets, console shift and aftermarket sunroof in '82. After much under hood cleaning, l came across a sticker that read: Notice, this engine is designed to be run on 98 or better octane. The bulb lit. At that time in Houston you could still get 105 octane. Ran down to 1/4 tank and filled up with the good stuff. Boy Howdy did that car love it. Woke up from a mediocre "old car" to a respectable bone stock runner able to get a legit 2nd gear prolonged "chirp". Never should've sold it.

[@kevincothron5089]

[@carlr.2322]

Fantastic video well done 👍👍

[@wrotenwasp]

Similar but not quite as rare was the 73-76 442. Although the compression was cut, you still got a 455 and ordered with say a 3.23 gear, installing a set of headers, they moved pretty good for a heavy car. Going a little further and for not that much money, an aluminum intake-holly carb, even a hotter cam/ 11" torque converter, 13s in the quarter weren't out of the question.

[@YernBelfus400]

Lol, no. It would take a LOT more than that to put an asthmatic pig like that in the 13s.

[@Benjam311]

I had a black '73 Cutlass with a 350. Not the 442, but the body was super similar. Loved that car!

[@wayawolf1967]

The purple GTO in this video shows how a classic can be ruined by its owner. Those over size wheels look absolutely terrible ! Just like a slammed pickup truck it ruins the total look and function.

[@grand73am]

True. It's not even a GTO. It's a Lemans GT, judging by the GT stripes along the side of it. Several of the cars in this video are not GTO's, but regular Lemans.

[@josephbarr511]

Emissions devices had nothing to do with the power decreases, as a smog pump takes nothing to turn. An 8.2:1 compression, suboptimal timing curve and pedestrian camshaft most certainly did. Now the catalytic converters of the mid 1970's on the other hand....

[@AMCmachine]

The Colonnades had in fact been slated for introduction in 1972 but a strike delayed them a year.

[@Oddzilla51]

Had a '73 LeMans Sports Coupe which looked exactly like the blue one shown, just with a different hood. Miss that car.

[@mattschiavone3383]

Essentially it follows the formula of the 1964 GTO . A mid size body with a big displacement engine. The 73’s across the board don’t get the love they deserve.

[@mfsb8473]

Grand Prix killed the GTO. They made over 150k in 1973 . Basically the same car.

[@grand73am]

Yes, the Grand Am was a brand new model for 73, so they were pushing it in their advertising, and pretty much ignoring the GTO. The GTO's sales had declined pretty badly by 72. So, 73 Grand Am sales were a big improvement over 72 GTO sales.

[@precisioncueservice6355]

I grew up in Detroit. In 1974, I was shuttled back and forth from swim practice by the mother of one of my teammates. She drove a 1973 GTO Station Wagon. It was her company car, her husband was a GM exec who was very highly placed at Pontiac. Super nice family, they owned the vacant lot next door to their house and had a go kart dirt track and let us neighborhood kids take a rip every now and then. I do not want to name them for obvious reasons. So, it was silver with black interior, buckets and console auto. It had the turned dash, GTO graphics, honeycomb wheels and the shaker. I don't remember what motor was in it but my guess it would be something special. I know the lady was about 5'4" and could not see over the shaker;) I got to ride in the front seat a few times, it was cool. Is it still out there????

Remember that they changed how they came up with HP numbers. NET and GROSS, and factory’s often just lied about it so insurance would be affordable , so buyers could afford a new car easier.

[@YernBelfus400]

Lol. SAE net horsepower is the ACTUAL horsepower. Gross horsepower numbers were bogus inflated numbers created for advertising purposes. For example, Pontiac CLAIMED as much as 370 horsepower for the 455, but in reality, the L75 455 only put out 250 SAE net horsepower at the flywheel, and even less to the rear tires. That's why the so-called "muscle cars" were so slow.

In 1983 I bought a 1973 GTO with the 455 for $150 in Orlando Florida. It was pretty slow off the line but had no trouble getting up to 145mph top speed. At between 100 to 120nph it was a nice handling car very stable. When I moved to Alaska in 1985 I sold it for $500 but have occasionally wondered what potential the car would have had if you pulled off the pollution control parts and built the engine.

[@YernBelfus400]

Lol, no. 145 mph was a physical impossibility for that car. IF you ever actually owned any such car, you'd know that. With 26" tall tires, 3.42 rear end gears, and the 4,000 rpm horsepower peak of the 250-horsepower RPO L75 455 engine, that vehicle would have a top speed of about 90 mph.

JoeJoe, your 455 equipped GTO probably had a 3.08 gear like My 74 Century GS 455 has. That makes your top end much more likely than the last responders 3.42 comment. My GS will do 140 ish, but i have a couple of power improvements. The A body cars GTO, Grand AM, Cutlass 442, Century GS and Chevelle when equipped with the larger engine options had a nicely heavy sprung suspension and sway bars - All handled amazingly at speed! They are allot more fun if you get your HP up to 400 +

Excellent topic! Well researched and presented. I like the look of the 73-77 Pontiac A-body for similar reasons I like the 70-72 Monte Carlo. That means really great - for someone else. They are not near enough the "real" performance design of the Chevelle 70-72, or Le mans 70-72 etc. So I would much rather spend $25000 on a 72 in complete, but grimy shape than a mint 73. Particularly with top of the line options in both. I would not restore any car beyond daily driver abilities. If I can't use it, it's of no use to me. Refershed engine, carb, distributor, transmission brakes and suspension. Maybe a new paint (orange, black, silver, yellow - something I like, regardless of original color) if it looks horrible. 15*8 inch wheels with 275/60 in the rear for sure.

[@peterhogan9537]

in 73 the Grand Am was taking over this area of the market.

[@grand73am]

Yes, the Grand Am was a brand new model for 1973, so Pontiac was pushing it in their advertising, and in their dealer brochures with full page pictures. The GTO got only a small mention and insert picture in the brochure, and rarely, if ever, had a magazine ad. Although there was that infamous edition of "High Performance Cars" that put a 73 GTO SD-455 on the cover proclaiming it as 1973 Car of the Year, before finding out that the SD-455 had been cancelled for the GTO 🙂.

[@kellynestegard5208]

I've had several mid-70s A body cars. My favourite to drive was the '73 Grand Am. The quickest was a '73 Malibu. Originally a 350 2bbl. single exhaust car. I added an Edelbrock performer intake, custom dual exhaust and a re-curved HEI distributor.. I had to retard the timing to stop the tires from spinning on wet roads. But I really like the B body cars; I'm currently building a '63 GP. 400 5 speed, SD Performance heads, long branch exhaust manifolds. Gonna be a nice 400hp cruiser.
