An insane Mustang Boss 429 drifting scene from the movie John Wick!

Even if you’re not a big movie fan, you have to see John Wick because of this rare Ford Mustang Boss 429. It was produced in 1969, when 859 cars were made, and in 1970 when only 499 were made, which makes it one of the most rare and valuable muscle cars ever.

The Boss 429 engine was derived from the Ford 385 engine. It used four bolt mains, a forged steel crank and forged steel connecting rods. The engine featured aluminum cylinder heads, which had a modified Hemi type combustion chamber which Ford called “crescent”. These heads used the “dry-deck” method, which means no head gaskets were used. Each cylinder, oil passage and water passage had an individual “O” ring style seal to seal it tight. The Boss 429 engine used a single Holley four barrel carburetor rated at 735 CFM mounted on an aluminum intake manifold that flowed well for its time.

However, the body of the Mustang was rather narrow to encompass the massive Boss 429 engine and as a result, Ford hired Kar Kraft out of Brighton, MI to modify existing 428 Cobra Jet and Super Cobra Jet Mach 1 Mustangs to properly fit the new Boss 429 engine. Kar Kraft was contracted by Ford to create the Boss 429, because Ford was stretching itself thin across a number of projects, such as the Boss 302 and its Trans Am version that competed in the SCCA Trans Am Series of races in the same years the Boss 429 was being produced for NASCAR.

The cars were rated at modest 375 hp (280 kW) and 450 lb·ft (610 N·m) of torque by the manufacturers, but actual output was well over 500 horsepower (370 kW). Some people have claimed it to produce 600hp or more.

The engine is said to be able to rev up to 9,000rpm for extended periods of time, which is impressive given the engines massive 7.0L displacement, though were factory limited to 6,200rpm for insurance purposes. It is said to be able to exceed speed over 175 mph.

No wonder John Wick went on a vendetta  spree for this!
