Amazing 1968 Mustang GT S-Code Fastback

This 1968 Ford Mustang GT Fastback carries the S-code designation Ford reserved for its 390-powered cars, a step below the legendary Cobra Jet but a genuine leap over the small-block base models. Fully documented with extended photos at MyRod.com, the car draws comments from owners who’ve spent forty years building their own fastbacks and buyers cross-checking every spec against the fender tag. See what makes an S-code car worth the extra attention.

A fastback Mustang GT with the right numbers-matching code stamped into its data plate can turn a routine walkaround video into something closer to a treasure hunt. This 1968 example wears one of the more desirable codes Ford ever offered on the platform, and the team documenting it clearly knows exactly what they’re looking at. Between the roofline, the back window, and the details buried in the interior, there’s a reason longtime Mustang owners keep circling back to this specific body style and this specific engine option above almost anything else Ford built that year.

What ‘S-code’ Actually Means

Ford’s engine-code system used a letter in the VIN to identify exactly which powerplant left the factory installed, and S designated the 390 cubic-inch FE-series V8 rated at 325 horsepower in 1968 Mustang GT trim. That distinguishes this fastback from the more common 289 and 302 small-block cars, giving it meaningfully more low-end torque and a deeper exhaust note, while still sitting a step below the legendary 428 Cobra Jet that would arrive mid-year. For collectors, an S-code car represents one of the sweet spots in the 1968 GT lineup: real power without the premium and rarity of the Cobra Jet.

The Fastback Shape That Defined an Era

1968 marked a subtle but important restyle for the Mustang, with a wider grille, revised side scoops, and sequential taillights that would go on to become one of the model’s most recognizable design cues. On the fastback specifically, the sloped roofline and louvered rear glass — a detail multiple commenters singled out as their favorite feature of this exact car — gave the GT a lower, more aggressive stance than the hardtop or convertible. It’s a shape that would go on to headline Bullitt the following year, cementing the ’68 fastback’s place in muscle car iconography.

A Car Documented, Not Just Sold

Quality Classics built this video around a full walkthrough rather than a quick sales pitch, pointing viewers toward an extended photo and specification listing on MyRod.com for anyone who wants deeper documentation before making a decision. That level of transparency — matching visible condition against a paper trail rather than asking buyers to take condition claims on faith — is exactly the kind of due diligence longtime classic Mustang buyers say they wish more sellers offered, and it’s a big part of why the video draws the specific, detail-oriented comments it does.

The GT Package, Beyond the Badge

Beyond the engine, the 1968 GT package added front disc brakes, a handling suspension, dual exhaust with distinctive quad tips, GT-specific badging, and a driver-focused interior with additional gauges. On an S-code car, those upgrades matter more than they would on a base six-cylinder Mustang, because the 390’s extra weight over the front axle makes the GT’s upgraded brakes and suspension genuinely necessary rather than cosmetic. It’s the difference between a Mustang that merely looks the part and one actually engineered to handle the power under its hood.

What Longtime Owners Bring to the Comments

The video’s comment section reads like a gathering of people who’ve spent literal decades around this exact car — one viewer describes forty years spent building a ’65 fastback clone, another recounts buying a Candy Apple Red ’68 GT off the showroom floor in 1967 for $3,500. Those firsthand recollections, arriving alongside technical notes about cam specs and exhaust manifolds for getting real power out of a 390, turn the comment section into its own informal archive of Mustang ownership history.

A Small Debate Over GT Nomenclature

Not every comment was pure nostalgia — one viewer raised a genuinely interesting question about whether a GT with an automatic transmission should technically have been badged GTA rather than GT, a naming convention some enthusiasts insist applied in earlier model years. Debates like that one are common in tightly documented Mustang communities, where badge codes, build sheets, and factory literature sometimes tell slightly different stories depending on the year and source.

Why S-code Fastbacks Hold Their Value

Among 1968 Mustang GTs, S-code fastbacks occupy a genuinely strong position in the collector market: rarer and more powerful than base cars, but more attainable than a documented Cobra Jet. Combined with a fully sorted example backed by real photo documentation, a car like this represents exactly the kind of Mustang buyers actively search for — enough performance and history to matter, without the six-figure price tag that comes with the most famous Mustang variants of the era.

The Market for Fully Documented S-code Cars

Buyers shopping for a 1968 GT fastback increasingly rely on exactly the kind of extended documentation MyRod.com provides alongside this video — VIN decoding, marque-specific data plate verification, and photo archives that let a buyer confirm originality before ever making a phone call. That level of transparency has become a genuine differentiator among classic Mustang dealers, separating shops willing to stand behind their claims from listings that simply describe a car as numbers matching without offering any way to verify it. For a car this specific and this collectible, that difference in seller transparency can be worth real money at resale, and it’s part of why comments under videos like this one skew toward technical questions about cam specs and exhaust setups rather than simple compliments. Serious buyers, in other words, treat the comment section itself as an extension of their own due diligence, cross-checking details against what they already know about S-code cars before ever picking up the phone.

Why Fastbacks Photograph Differently Than They Drive

Static photos of any 1968 fastback tend to flatten the car’s most distinctive feature — the way that sloped roofline and reverse-angled rear glass actually change the car’s visual weight depending on the angle and the light. Quality Classics’ video walkthrough solves that problem by circling the car in motion, letting viewers see exactly how the roofline transitions into the rear quarter panel and how the louvered back window catches light differently than a flat rear window would. For buyers used to shopping classic cars purely through static listing photos, that kind of full-motion documentation is a meaningfully better way to judge a fastback’s actual presence before ever seeing it in person.
