Real S-Code: 1967 Ford Mustang GT 390 Project

Disclosure: This site may receive compensation from some link clicks and purchases.

This 1967 Ford Mustang fastback listed on eBay checks several important boxes for serious Mustang enthusiasts, starting with the fact that it is confirmed as a real fastback and a factory S-code car. Originally, this Mustang left the factory as a 390-powered, 4-speed GT, which immediately places it in a desirable performance category from day one. Thanks for the tip, Curvette!

Today, the drivetrain setup has changed. The car now has a 351 V8 with an automatic transmission installed. The seller notes that the motor turns over, but it still needs to be wired, and their original plan was to remove it. That leaves the next owner with clear options—either finish the current drivetrain installation or return the car to a more factory-correct configuration depending on goals and budget.

Structurally, this Mustang is described as a very solid car, which is often the hardest part of owning one of these fastbacks. The seller confirms that the apron stamp is still present, which helps authenticate its original identity, and it also retains the correct 9-inch rear end for a 1967 model. Those details matter to collectors who care about originality, even when a car is in project form.

This Mustang also has GT options, along with front disc brakes, both of which add to its appeal as a performance-oriented foundation. The VIN prefix confirms its S-code origins, reinforcing that this was not originally a base-model car upgraded later—it began life as a higher-performance Mustang.

Finished in black, with patches of repair work and flash rust, the car currently has a clean title, and it’s being sold as a project vehicle. What makes this Mustang especially attractive is the combination of its real fastback body, documented S-code history, and solid condition. Many fastbacks on the market today started life as lower-spec cars, but this one carries genuine performance pedigree from the factory. Even though it’s no longer wearing its original 390 and 4-speed, that heritage still gives it added weight in the Mustang world.

For the right buyer, this car offers flexibility. It can be built into a modernized street machine using the existing 351 setup, or it can be taken back toward its original GT, S-code roots. Either direction starts with a solid, authentic fastback platform—something that continues to get harder and more expensive to find.

Would you keep this Mustang as a restomod with the 351, or would you chase down a period-correct 390 and return it to its original S-code GT form?

    Wow that was quick. I sort of question what value an S code 390 adds if it’s not in there anymore. Even if you could get a period correct engine to put in, it’s not original anymore.

      I believe it still adds value. One could build another year-correct 390 engine to the original spec – and install the 4spd trans – and have exactly the original performance and look. Even though this would not have the same monetary value as the numbers-matching version, it would still have more value than a more common Mustang that was produced with, for example, a 302 2bbl.

        I agree with Geoff, returning this back with the period correct components would be the best way to go, and the next best possible value for this rare Mustang.

    The auction ended with a high bid of $20,300, which did not meet reserve. I’d be surprised if the seller doesn’t relist it, he’s sold several cars, some featured on this site, over the last 90 days, those that didn’t sell the first time were relisted.

    It’s tough, but still a fastback Mustang. Which means someone will eventually buy it.

    I can see why it didn’t sell. Original engine gone, automatic transmission installed, but clutch pedal still dangles. Fairly rough body with rot noted underneath, and the interior needs work, especially that cracked dash and trim. Bumpers gone, and some pictures that look like somebody had a few before placing the ad…

    Looks like a good project. To make it a “real mustang” S code would have to gut that “baby motor” and slushbox and put back the “real thing” 390 and a 4 speed manual. IMHO the price is a little high given the sate it’s in but maybe that’s just me.

    A Coyote motor will not fit without major re-work to the engine bay and shock towers. A 351 Windsor is probably a better choice in the long run as 390 S code motor was super heavy in these from the factory.

    I owned one of these in 68. Bought it from a guy who bought it new and didn’t like. Mine had a 3 speed and i drag raced it. Don’t say it didn’t have the 3 speed because it was a special order car and it did. It also had ac. After daughter was born had to sell but it was a fun 4 years while I had it.

    It’s a shame that the original 390 came up missing. Many parts are specific to this application. Intake, linkages, exhaust manifolds, and more. A friend of mine found himself in this exact situation. After tallying the cost of buying or building an appropriately equipped 390 he sold the car as was.

    My buddy had one of these bought a brand new in Wilmington Ford, but our gym teacher paid 3800 bucks for 351 Cleveland with a four speed at the slats and back bright red white interior oversize tires in the back don’t make them like that anymore Went across the desert 148 miles an hour heading towards California great times

    It looks like the one another Mustang seller that’s featured on BF lists – but most pictures are out front of that Mustang guys place. This Mustang seller seems to have a back yard porch for display pictures ?
