This 1970 Ford Mustang Boss 302 was personally owned and driven by Parnelli Jones, an icon of American racing and the man who won the 1970 Trans-American Sedan Championship driving a car much like the one you see here – a Boss 302.

The Boss series of Mustangs were famously named almost by accident, the designer who was in charge of the Boss project was Larry Shinoda, and the project was being conducted in utmost secrecy so as not to give forewarning to the team behind the Camaro.

Whenever he would be asked by other Ford employees what he was working on, Shinoda would just say “the boss’s car” referring to company president Semon “Bunkie” Knudson who had approved the project, and leave it at that.

It became the default name for the car, and the company decided to use it on the production models – the Boss 302 was the car homologated for racing in the Trans Am series and the Boss 429 was the car homologated for NASCAR which had a higher maximum engine capacity.

Mustangs had been racing and winning almost since the model was first introduced and largely thanks to the work of Carroll Shelby and his team’s work on the Shelby GT350. The Boss 302 would be developed internally at Ford specifically to beat all the new pony cars that had been released in the 1960s after the Mustang to challenge the Ford’s lead in the sales figures.

Trans Am racing was hard fought, so it was clear the cars were going to need to be significantly modified to win. It was also clear that a road-legal version of the cars were going to need to be available to buy to the general public to meet homologation requirements.

The Boss 302 was fitted with lowered competition suspension, a Hurst shifter, front disc brakes, thicker sway bars, reinforced shock towers, heavy duty spindles, and a 4-speed manual transmission.

The cars are instantly recognizable for their “hockey stick” decal that runs down both sides, and for the front spoiler and rear deck wing. In the engine bay you would find the specially prepared 302 cu. in. (5.0 litre) V8 with a thin-wall black casting that used four bolt mains, screw in freeze plugs, and unique heads with better flow characteristics and a canted valve design.

Engine power was rated at 290 hp, the standard Mustang 302 produced 220 hp up to 230 hp with the four-barrel carburetor. The 0 to 60 mph time was 6.9 seconds, good for the era, and the quarter mile time was 14.6 seconds.

After building the Boss 302 for the 1969 and 1970 model year Ford discontinued the model for 1971. The original survivors are now much sought after but there are a staggering number of “tribute” cars out there, so detailed inspections to ascertain authenticity are highly recommended.

The Parnelli Jones Boss 302 Shown Here

The car you see here was formerly owned by Parnelli Jones, as mentioned further up he’s the man who drove one to victory in the Trans Am championship in 1970 for the Bud Moore team ahead of Team Penske’s Javelins.

It was restored by Mark Brown and GS Johnson of the Boss 302 Registry to Parnelli Jones’ personal specifications in 2006 and it remained in his possession until he sold it to Brown in 2019. Impressively the car has accumulated just 2,000 miles since the restoration, leaving it in almost-new condition throughout.

Another claim to fame was that this was the cover car of Mustang Monthly magazine in May 2007, and it was featured in Mustang Times magazine in May 2008.

The car now comes with a Parnelli Jones signed Ford plaque, a photograph of 2003 title assigned to Parnelli Jones, a Parnelli Jones signed declaration of ownership, and a PJ Boss California license plate.
