Late first-gen Mustangs usually make for the perfect muscle car, and if you can’t find a nice 1969 model year car, the 1970 variant should do just fine, especially if your ideal Mustang is supposed to have a more substantial road presence.
Let’s talk about the Boss. No, not your boss, but the Boss. Arguably the greatest spec you can get on a vintage Mustang – be it the Boss 302 or the 429.
What’s the difference? Well, the former was built in order to satisfy Trans Am rules, while the goal of the latter was to homologate the Boss 429 engine for NASCAR use. Both specs went on to receive critical acclaim, but it’s the 429 unit that ultimately stands tall as one of the greatest engines ever to be fitted to a Mustang.
Between the two Boss models and the Mach 1, the Mustang certainly doesn’t need any other top-end specifications. However, have you ever heard of the Boss 427? No? Well, that’s only because it doesn’t exist, at least not formally. Yet, you’re staring at one right now, and you can even buy it for $99,950.
Full disclosure, this Mustang has been featured on our website before, back in April of 2022 when the asking price was $129,950. It looks like it’s gone down in value since, but that’s probably because $130k was way too high of an asking price, regardless of how nice of a build this is.
This is a fully restored vehicle, powered by a Ford Racing Crate 427 motor with Sniper EFI fuel injection, aluminum radiator, twin electric fans, a serpentine belt system, plus the MSD distributor and ignition box. The engine is mated to a Tremec five-speed manual gearbox, working alongside a hydraulic clutch and a 9” rear end.
Other noteworthy upgrades include the LED headlights, front and rear sway bars, Scott Drake leaf springs, Wilwood disc brakes (front), ceramic coated headers, and the adjustable coil-over springs.
As for convenience features, we count the Vintage Air climate control system, power steering, digital gauge cluster, Bluetooth stereo with a 5-channel amp, four speakers and an 8” subwoofer, plus the Billet hood hinges and a trunk-mounted battery.

It’s hard to say exactly how much power this Mustang is putting down, seeing as how the ad doesn’t specify any performance figures. If I had to guess, I’d wager about 600 horsepower. It’ll be quick, that much is certain.
This or a Boss 429?
Even though technically, this so-called “Boss 427” Mustang isn’t something you’ll see every day, it certainly doesn’t have the allure of the original Boss 429. That there is probably the most desirable Mustang specification ever made and just because we can, we’d like to remind you that the Boss 429 Mustang came out on top in our All-Time Best Classic American Muscle Cars feature.
In the end, it came down to the Boss 429 and the Charger Daytona, and we just had to give it to the Mustang.
Sergiu got to experience both American and European car "scenes" at an early age (his father drove a Ford Fiesta XR2 supermini in the 80s). After spending over 15 years at local and international auto publications, he's starting to appreciate comfort behind the wheel more than raw power and acceleration. Full profile
