1970 Ford Mustang Boss 302

This 1970 Ford Mustang Boss 302 was assembled in Dearborn, Michigan on March 27, 1970, and retains its factory color combination and options. Power is derived from a G-code 302ci V8 that is upgraded with a Holley carburetor and backed by a 4-speed manual transmission with a Hurst shifter. This Boss comes from three years of garage-kept ownership by the seller and is accompanied by documentation including a factory build sheet, a Marti Report, spare parts, and more. Finished in yellow with black hockey-stick stripes over a reupholstered black vinyl interior, this first-generation Mustang is now offered with spare parts, a Marti Report, a build sheet, and a clear California title in the seller’s name.

Beginning in 1969, the Mustang was offered with Trans-Am racing series-inspired performance packages and this example from 1970 bears a Boss 302 designation, so-named for its drivetrain. The exterior was estimated to be refinished in the mid-1980s and changed from the factory Bright Gold Metallic (K) color scheme to Grabber Yellow over an original straight body. Hockey-stick stripes and Boss 302 decals were applied in the factory layout, and other exterior treatment includes chrome bumpers and handles, a black lower front air dam, color-keyed racing mirrors, rear window louvers, and a rear deck spoiler. Taillights are housed within a black bezel bearing a round Mustang badge at the center, and dual exhaust outlets are located under the body.

Magnum 500-style 15” five-spoke mag wheels are wrapped in BF Goodrich Radial T/A raised-white-letter tires. Suspension underpinnings have been sorted according to the seller using period-correct components. Braking for the Boss 302 comes in the form of power-assisted discs up front and drums in the rear, and power-assisted quick-ratio steering was standard equipment.  

The all-black interior was previously re-trimmed in using original materials, starting with reupholstered vinyl high-back bucket seats and extending to the door panels, dash, headliner, and newer carpeting with embroidered Mustang-logo floor mats. According to the Marti Report, this Mustang came outfitted with the Decor Group, and the cabin is accented in woodgrain trim is featured across the dash face, door panels, and steering wheel rim. Additional amenities include a T-handle Hurst shifter, a push-button AM/FM radio, and pop-out rear quarter windows. An electric clock is featured at the passenger side of the dash but is inoperative.

Instrumentation includes a 120-mph speedometer, an 8k-rpm tachometer, and auxiliary gauges for fuel level, coolant temperature, voltage, and oil pressure. The five-digit mechanical odometer reads 48k miles, although true mileage on the chassis is unknown.

The G-code 302ci 4V Boss V8 carried factory ratings of 290 horsepower and 290 lb-ft of torque, and this example has been upgraded with a Holley 750-cfm carburetor and a new distributor. The surrounding engine bay is fully detailed in a factory matte black finish and features dress-up items such as chrome-finished air cleaner and valve covers. Power is directed to the rear wheels via a 4-speed close-ratio manual transmission and a 3.50 conventional rear axle.
