1967 Mustang Fastback 429 Boss

The Boss 429 Mustang is a high performance Ford Mustang variant that was offered by Ford in 1969 and 1970. Engine builder Jon Kasse currently reproduces the cylinder heads that make up the “boss 9” engine architecture.

Southern eighth-mile grudge-match staging lanes are often filled with LX Mustangs, G-bodies, second-generation Novas, and fourth-generation Camaros. They’re inexpensive and feature tons of room for performance upgrades. Buried in those lanes, you may discover this gem: an original 1967 Mustang Fastback. It’s a steel-bodied car with immaculate paint and stellar craftsmanship designed to turn heads and blow the tires off the competition—and it doesn’t have a LS under the hood.

The Boss 429 is easily one of, if not the most legendary engines Ford ever produced. Originally designed and built to compete against Mopar’s 426 HEMI, the Boss became an instant classic. This fastback uses that classic Boss 9 look to wow those taking a look under the hood. However that famous valve cover is where the similarities between this powerplant and the original 429 starts to fade. This is a one-off, all-aluminum, 600 cubic-inch Boss 9 block. The engine features Holley Dominator electronic fuel injection, a custom Hogan sheetmetal intake and two Nitrous Outlet dry foggers. The engine also features a Winberg Billet Crank, Oliver Rods, and Diamond Pistons, along with a long list of supporting mods. All told it is said to produce 1,800 horsepower!

The interior of the fastback is all-business. It features carbon-fiber floors, a custom race seat, and custom sheetmetal done by AP Race Cars. A chrome-moly 25.2/25.3 certified cage keeps the driver safe in case of an accident along with an onboard fire suppression system.

Ever since it was introduced to the market in 1964, the Ford Mustang became the most popular muscle car ever and an American car industry icon that gathered the attention of many car enthusiasts worldwide.

Buying and owning a muscle car is more than just a hobby; it’s a dream come true for many. The Mustang Boss 429 is one of the most precious classic cars due to its rarity since less than 1360 units of these cars were ever manufactured. And obviously, a much lower number of these are still in existence nowadays. Although there are continuation models of Boss 429 around, none of them quite hold the same gravitas as an original classic Boss 429.  Add this to the great feeling you can have while owning a rare classic car with a powerful engine, excellent exhaust note, and acceleration that is fast even by today’s standards.
