When it comes to classic muscle cars, late first-gen Mustangs, particularly the 1969 and 1970 models, are often considered perfect candidates. If you can’t find a 1969 model, the 1970 variant can also offer a substantial road presence.
Let’s delve into the Boss Mustangs. Not your workplace boss, but the iconic Boss Mustangs – the Boss 302 and the Boss 429. The former was crafted to meet Trans Am regulations, while the latter aimed to homologate the Boss 429 engine for NASCAR. Both versions garnered significant acclaim, but it’s the 429 that stands out as one of the finest engines ever fitted into a Mustang.
Amidst the Boss models and the Mach 1, the Mustang seems to have all the top-end specifications covered. However, have you heard of the Boss 427? Probably not, because it doesn’t officially exist. Yet, here’s one for sale at $99,950.
Full disclosure, this Mustang was previously featured on our website in April 2022 with an asking price of $129,950, suggesting a decrease in value. Regardless, the initial price was steep.
This fully restored vehicle boasts a Ford Racing Crate 427 motor with Sniper EFI fuel injection, coupled with numerous enhancements like an aluminum radiator, twin electric fans, a serpentine belt system, MSD distributor and ignition box, Tremec five-speed manual gearbox with hydraulic clutch, and a 9” rear end.
Additional upgrades include LED headlights, front, and rear sway bars, Scott Drake leaf springs, Wilwood front disc brakes, ceramic-coated headers, and adjustable coil-over springs. Convenience features comprise Vintage Air climate control, power steering, digital gauge cluster, Bluetooth stereo with a 5-channel amp, four speakers, and an 8” subwoofer, along with Billet hood hinges and a trunk-mounted battery.
Though the ad doesn’t specify performance figures, it’s estimated to produce around 600 horsepower, ensuring impressive speed.
Choosing between this “Boss 427” Mustang and a Boss 429 is a tough call. While the Boss 427 may be unique, it lacks the allure of the original Boss 429, which is widely regarded as one of the most desirable Mustang specifications ever. In our All-Time Best Classic American Muscle Cars feature, the Boss 429 Mustang even triumphed over the Charger Daytona, solidifying its legendary status.
