Available for auction is this 1970 Ford Mustang Boss 302 finished in Yellow over a black interior. Ford introduced the original Mustang Boss model in order to homologate the specially developed Small Block V8 engine for competition in the SCCA’s Trans-Am road racing series. In addition to its 302ci engine, the Boss also received an upgraded suspension and braking system. A lifelong California car, this three-owner 1970 example underwent a complete nut and bolt restoration about 10 years ago with the goal of creating an MCA Gold concours show car. The restoration process was carried out at 60k miles and is said to have used all original Mustang parts except for an upgraded camshaft and Edelbrock mufflers. With less than 5k miles traveled since the completion of the restoration, this outstanding Mustang Boss 302 is now being offered for auction by its seller out of Massachusetts.
This Boss 302 comes finished in Yellow and features signature “hockey stick” stripes, a front spoiler lip, shaker hood scoop, and rear window louvers. As a 1970 model, this Mustang also received a restyled front grille and headlights flanked by inlet vents on either side. All the original metal bodywork is said to have been retained during the restoration as there were no signs of rust throughout the body, additional images are provided in the photo gallery. This Mustang rides on a set of Magnum 500–style 15″ wheels which come dressed in a set of BF Goodrich Radial T/A tires showing date codes from 2018.
Inside, the cabin features door panels and high-backed front bucket seats upholstered in black vinyl along with a matching dashboard and a Hurst shifter. The cabin is said to have been completely refurbished during the restoration using new-old-stock Mustang parts including the hood-mounted tachometer.
This Mustang carries a G-Code 302ci Small Block V8 engine featuring a special thin-wall block casting, 4-bolt mains, screw-in freeze plugs, and Cleveland-style heads with a canted valve design. In stock configuration, this engine can produce as much as 290 HP. The engine in this example was fully rebuilt during the restoration and equipped with upgraded cams and Edelbrock mufflers. The rear wheels are driven by way of a rebuilt and numbers-matching 4-speed manual transmission. Other performance-oriented features of the Boss 302 include a lower ride height, front disc brakes, larger sway bars, heavy-duty spindles, and reinforced shock towers. Some service records are provided for reference in the gallery along with images of the undercarriage.
This sale will include service invoices, the original warranty booklet, and a clean title. One of the most recognizable muscle cars ever made and a true icon of American automotive history, this Mustang Boss 302 would make a beautiful addition to any car collection.
