General discription

COMING SOON/EXPECTED : 

This extremely rare 1973 Pontiac Firebird Trans Am 455 SUPERDUTY. Its one of only 180 ever produced Super duty's with automatic transmission and a possible one of one car in this color combination and with these options ever build. The car is in the Superduty registry and its the only one with these combinations in the world today. On top of that this car is also completely in original condition and it still carries its complete numbers matching SD engine and transmission. It's also a true real low mileage car with only 31000 miles ever driven. The car is also equipped with almost every available factory extra cost option. 

The 455 Superduty Transams were the last and fastest muscle car's that were ever produced in the early 70's. The Superduty engine was developed by Pontiac as a pure race engine and it found its way into street production cars in 1973. The Super duty engine is a completely different engine than the 455 and 455HO engines that Pontiac had produced earlier on and although it maybe came to late to compete in a dying muscle-car market because of the upcoming fuel crises and ever more restricted environmental rules of that era, but man what a monster had the produced. 

The short block was a complete new design with 4 bolt main caps and many other special provisions to be able to make it strong and ready for some serious street or strip racing programs, but at the same time the head design was new as well as the intake, oil system, and exhaust manifolds were upgraded. In the first test phase, it made close to 600hp !. But seeing the engine was also designed for use in street cars Pontiac engineers had to make compromises to make that happen. The compression ratio was lowered and at the last minute, a bit milder camshaft was used to meet the required rules that were already very strict in 1973 and which had killed all other brands' true performance engines. But even then the engine was a monster and performed very well indeed. To get these cars also sold, 
Pontiac had to heavily underrate the factory HP rating in the sale's brochures to 310 hp and a mere 395 ft.lbs ( 535 NM ) because otherwise, owners couldn't get these car's insured anymore in 1973. However, once on the street's these Superduty equipped cars had way more power than that and were estimated to have close to 400+hp or more and 550-600ft.lbs ( 750+NM). 

The proof of that was given by a dragrace, performed by an independent journalist from Hot rod magazine in 1973 where he took a completely stock, Automatic transmission equipped Superduty to a staggering 13,54 seconds down the quarter-mile with a 1/4 mile trap speed of 105 mph... on street tires !.  A record that wasn't broken until in 1993 by the Corvette ZR1 more than 20! years later.... The Corvette ZR1 produced close to 500hp so its needless to say that Pontiac's Superduty's were absolutely very underrated by the factory back in 1973. 

Some muscle cars specialist dare to state that the Pontiac 455SD engine was the absolute best performance engine ever designed in the late 60's and early 70's and onwards and it would outrun any street 426 Hemi from Chrysler, any Chevy's 427 ZL1 engine, or no matter what other Street based V8 engine design that was built at that time. 

It's needless to say that this Superduty therefor is not only a very rare car but also might well be the fastest classic muscle car ever produced. The fact that there where only so little build and sold was due to the fact that these engines were a very expensive option to ad on the already expensive price tag of a base 455 Trans am combined with the fact that the fuel crisis and insurance cost were a huge obstruction for most buyers at the time also. Pontiac was also held back with the production of these great engines because the emission rules that were changed almost daily and Pontiac engineers had a big job fighting against that. This meant that the Superduty engine options came available very late in the production year, which also was cause for the small production numbers. 

The car we present to you here is one of those very rare and highly desirable and collectible Superduty's. The car spend almost its entire life in the dry states of Texas and Missouri and was well taken care of and pampered by its 2 original owners and never raced or abused in any way, hence the fact it's still equipped with its original driveline today. As many of the original Superduty cars were used for drag and street racing with tuned up engines which also meant many of these cars were crashed and engines wrecked. Not this car.

Its painted in the factory original Cameo white color with black deluxe bucket seat interior that is one of the best colors for the Trans am's sleek and modern design. Its equipped with many desirable options as you can see below and its condition is fantastic. The car is completely damaged and rust free inside and out and the engine and complete driveline is in as new condition as well. At some point in its live, the car received a mild restoration and every detail, the complete brake and suspension and steering system was rebuild with factory original components that make's the car appear factory new until today.

If you ever 
want to own one of the true legend's and one of the most beautiful and best driving and fastest classic muscle car ever designed, then this is it !. With it being a true One of One car in its options and condition, and with only around maybe 100 of these cars in existence today worldwide you can be sure that you will be the owner of something truly exclusive.

  • Guide: Matching numbers

    In the collector car hobby, most investment-minded buyers are acutely interested in a specific car’s history. One of the main aspects of that history is an original or, as most people state it, numbers-matching drivetrain. At pedaltothemetal muscecars we feature a plethora of original and numbers-matching classics including ‘Cudas, Road Runners, Chevelles, Camaros, Corvettes and Trans Ams. And, if a potential buyer knows how to properly identify and interpret certain manufacturing codes, they can further validate their car’s history, or on request we can provide it.

  • Vehicle claims and descriptions

    Vehicle/product descriptions, representations and claims on or offline are based on what can be seen by the human eye, documentation, previous professional experience, opinion, factory claims, and, or, information passed on to us by previous owners or restorers. It's to the best of our knowledge that everything we advertise has all indications of being that claim. Please inquire as to what documentation we have on the vehicle you are purchasing or feel free to ask any additional questions you might have, But by no means you can accept our answers as facts as the are our interpretation and might not match yours. It is with integrity and honesty that we describe our cars, but they are in fact, up to 50 years old, may have had many previous owners, modifications or alterations that are unknown to the us, so it's not possible to verify everything about every car in detail. Thereby the stated conditions or details of a car can never ever be taken as a fact. As always we welcome personal inspections and or independent appraisers prior to a sale. Incase we speak of "Original" or "Matching numbers" it means that we asume that to be the case, but with old classic cars thats by no means a guarantee. So please feel free to verify that in person or with a third party.

    Pttm goes a step further than almost every other seller(s), as we also do a full inspection of our vehicles prior to having them for sale in our showroom and make repairs improvements if needed so. And when a vehicle/product is sold we give it a full service check before you receive it !
