@_slice_: // 1969 Mustang // An 800-horsepower 1969 Mustang big block is a custom restomod. Factory '69 big blocks (like the 335 hp 428 Cobra Jet or 375 hp Boss 429) require significant aftermarket upgrades, such as a bored/stroked 460ci V8 to 557ci, or modern supercharged engines to reach 800 hp. || #edit #ford #cars #mustang #v8 || clips from : AutotopiaLA ||
