“I really enjoy this car,” says Tim. “Compared to the other Mopars, it handles like something modern, and it responds; it’s definitely the most fun car in my collection. I normally keep a set of radials on it so I can take it out when I want to just drive. I bought it thinking I’d resell it; after driving it, now I will never sell it.”
Astronaut Neil Armstrong talked of mankind's steps as he became the first person who ever walked on the moon, and for many musclecar fans, what was happening back on earth was also pretty far out, too. After all, the auto manufacturers had announced they would be pushing the limit for the 1970 model year. Chrysler's Six Pack and Hemi engines would be in a new line of sporty E-bodies, Ford had 429-cid engines in street (SCJ) and race (Boss) trim, and GM lifted its 400-cid limit in midsize performance models.
Buick was one of the more 'stoic' brands being built, just below Cadillac in the GM hierarchy of excellence. However, that had not kept the Flint, Mich. company from engaging in projects with a more youthful outlook. The GS-series models based on the Skylark had carried that banner forward during the 1965-1969 years, using the thin-wall cast Buick big-block at 400" for power after its arrival in 1967. For 1970, both the 400" and the 430-cid Buick luxury engine were superseded by a new package that pumped out a big 455" cubes. It should be remembered that the 455" used by Buick was not the same as the 455" displacements offered by Pontiac or Oldsmobile (which were also different from each other).
Buick made use of an over-squared (bore larger than stroke) design in the new engine, and offered it in different states of tune. In the new GS455 model, it was paper-rated at mere 350 horse at a lowball 4600 rpm, with 425 lb./ft. torque. Buick was notorious for underrating true performance numbers, perhaps to persuade buyers to consider other options in the GM line, and most likely to allow the division to fly beneath the 'respectability' flag of its banker and broker audience. Most people in the know will quickly tell you that Buicks could hold their own against most anything else that was factory-available once that 455" lung became the mill of choice.
Pontiac offered various states of tune for their 400” and new 455” mills (the Ram Air II,III, and IV packages), while Olds had what they called the W30 option . Buick used a hop-up they called Stage 1 available from the factory, and a Stage 2 that was dealer-installed. The Stage 1 program, begun in 1969, continued into 1970 with a hotter cam and reworked heads with larger valves. That got you another 10 horsepower at a mere 4600, to 360 hp on paper (with the true max rpm power ‘sweet spot’ someplace well north of 400 ponies) and a monstrous 510-lb/ft of torque at 2900 rpm. The cars were capable of times in the mid-13s, impressive when considering that these were fully-optioned machines with the same standard of quality that all Buicks were noted for.
But getting back to our space-age analogy, the names Saturn Yellow and Apollo White would be enshrined forever as special to Buick fans when the Chicago Auto Show opened in early 1970. Buick had pulled out all of the stops with a new model they called the GSX. Announced in the print advertising of the time as a Limited Edition, the X was a special $1195.87 option on the GS455 hardtop. Only the two aforementioned colors were offered, using black graphics and black-out hood, spoilers fore and aft, a hood-mounted tach, upgrades to the suspension, and more. Optional G60-15 Goodyear Polyglas tires, the last hurrah of OEM street bias-plies as the radial age dawned, made it handle. A fully-dressed GSX could come off the showroom floor with a sticker price of approximately $5,000, not small change in that time, but its appearance and notoriety were guaranteed to turn heads in any setting.
The car in the Wellborn collection is one of 188 that received the 455 Stage 1/M22 rock-crusher four-speed combo. There were only 678 GSXs produced in 1970, and the few examples produced after that first year suffered from the decline in compression ratios that affected all GM models. Like all other 1970 GSX models, the car in the collection has a black vinyl bucket seat interior, plus the Sonoramic radio.
“We wanted to have an example of all the midsize GM performance models from 1970,” remarks Tim Wellborn. “The GSX is a legendary example of just how extreme things became. I like driving this car because it really is a Buick in terms of its build and ride quality, but it is also a real musclecar in terms of performance.”
The 1970 GSX would be a true legend of the age; the relative few that were built were treasured by their owners and made no bones about their ability when put to the test during a stoplight or highway joust. As a result, it has a fitting home in the collection, and a most deserving vehicle of the title 'muscle car.' Even (or perhaps especially) as a Buick…

Musclecar paint schemes grew more and more crazy in the late 1960s, and Chrysler’s legendary foray into the world of HIP (High Impact Paint) began in 1969, when five special paint colors debuted. These paint hues were actually an extra cost option, so such colors can add to a car’s collector value today. Things got even more extreme in 1970; the Charger here is painted code FM3, known as Panther Pink.
Other Dodge HIP colors in 1970 were EK2 Go-Mango (yellow-orange), EV2 Hemi Orange (or red-orange), FC7 Plum Crazy (purple), FJ5 Sublime (light-green), and FY1 Top Banana (yellow), with FM3 Panther Pink and FJ6 Green-Go (a deeper green than Sub Lime) both added at mid-year. For Plymouth, the corresponding colors were EK2 Vitamin C Orange, EV2 Tor-Red, FC7 In-Violet Metallic, FJ5 Limelight, FY1 Lemon Twist, with FM3 Moulin Rouge and FJ6 Sassy Grass Green added later.
Indeed, it appeared that all of Detroit had gone psychedelic by then; colors plus wild graphics and styling options abounded from the Big Three – scoops, blisters, wheels and wings. And the displacement wars were waging – the 440 was joined in 7+ liter territory with GMs 454” and 455” inch plants in the midsize body range that year. Chrysler did not add cubes for 1970, choosing instead to add more carbs, a package Dodge called the Six Pack.
After showing up in a handful of Road Runners and Super Bees in 1969, the 440 Six Pack was the newest mill for the Dodge line-up in 1970, available in the B-Body and E-Body performance lines and rated at 390 horses. It featured heavy-duty internals and the trio of Holley two-barrels just like the 1969 version, and its main benefit was more fuel throughout the RPM range. Indeed, it was a better street choice for many than the Hemi, since it achieved quicker peak horsepower on a lower torque curve than the 426 ‘elephant’ did. The Six Pack in this Charger R/T is coupled to a Torqueflite and a highway happy 3.23 SureGrip 8 ¾ differential.
Outside, this particular car was optioned with the white vinyl top and the longitudinal sport stripes that were new for 1970 (you could still get the Scat Pack rear-wrap stripe as well). Though it was an R/T model, it did not get a deck wing, and there was no ‘sport hood’ available yet for the Charger (that year’s Road Runners, GTXs and Coronet R/Ts, on the other hand, offered several variations). It also left the St. Louis assembly line with both left and right outside sport mirrors, tinted windshield, and front and rear bumper guards. Magnum 500 road wheels (code W23) and Goodyear Polyglas tires were part of the mix as well. . The F70 tire was the largest available from the factory on this model, but this example now uses the wider G70-14 replacements.
Inside, our Charger came with the scarce hounds-tooth buckets, covered with black vinyl featuring white cloth insets, plus the console with floor mount, woodgrain appliqué dash with the standard Rallye cluster design (but no clock or tach), AM radio, and the black steering wheel with lower ½ horn ring.
So, who ordered it that way? Believe it or not, this was a sales bank car. These were models built by the factory for general distribution, and sales bank cars helped keep the assembly line busy and helped assure that a ready supply of cars was on hand for the dealerships. It was built very late in the 1970 year, July 10 being the scheduled production date, and may well have been done to help clean up what was laying around the plant since the Charger would undergo some serious restyling the following model year (which would actually begin a little more than a month later).
Tim and Pam Wellborn spotted it at the Mopar Nationals in 2004, and Pam knew it fit her outlook on life to a ‘T.’ Owner Dale Gyorvary had decided to sell it, and it is believed to be one of just two FM3 Six Pack Chargers built that year; the price was reasonable and Pam wanted something that could be driven around. The Six Pack fit that final requirement perfectly.
“What I like best is the color obviously, and I love ‘70 Chargers, unlike my husband, who’s crazy about the ‘71s,” she says with a grin. “The car was done, we didn’t have it do anything to it, and the white accents make this car a standout. It also has that hounds-tooth interior, and it was the only 440 Six Pack in our collection at the time. Those are all the reasons I gave Tim when I said ‘we need this car!’ that day.”
There was one other important reason: she and Tim had first dated in a 1970 440 Charger many moons ago. That car, unrestored and painted Jamaica Blue, is still in their collection as well.

Survivor big-block musclecars are a unique breed of collector car. After all, when you signed your name to that loan for a machine with 400+ cubes and a race-inspired styling, the intention was to drive. What changed all of that was the insurance crisis that raised rates tremendously right in 1970, the gasoline crunches that ensued later in that decade, and the understanding by some owners that, as the hit song by Jim Seals and Dash Crofts recalled, ‘we may never pass this way again.’ And indeed, for machines like the LS6 Chevelle, that sentiment proved true – 454 inches with 450 ponies on tap were not long for this world. Some were tucked away, while others, like this one, were simply well-cared despite their use.
Tim and Pam Wellborn had begun gathering examples from that era’s Mopar heritage many years ago, but as their dream for their Musclecar Museum grew, they also wanted examples of other makes. After all, 1970 was a pinnacle year for performance supercars – the E-body Mopars, the Super Cobra Jet Falcon and restyled Boss Mustangs, and the upstart AMC Rebel Machine joined the fold, while GM finally dropped the corporate edict that kept anything over 400” officially out of mid-size musclecars.
So right off the factory floor came the big 455” Pontiac, Olds, and Buick beasts, examples of which all now reside in the Wellborn collection. At Chevrolet, the legendary 427 ‘rat’ motor was superseded by a new over-square powerplant with a 108.0 mm bore and 100 mm stroke; 7.4L is the math, but converted to inches (4.251 x 4.00) the designation was 454.
