Why it matters
The 1970 model year was the second and last for the first-generation Boss 302. It was the year Ford's Boss Mustang won the Trans-Am manufacturers' championship, and the production car gained new stripes and 'Grabber' colours while keeping the 290 hp rating.
How rare is it?
Six separate kinds of rarity – never combined into one number.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model production1970: 1969 Boss 302s built | 1,6284 | Factory production | Independently researched |
| Total model production1970 Boss 302s built | 7,0131,2,3 | Factory production | Disputed |
Sources differ: RM Sotheby's (2015) and Heacock Classic say 7,013; other RM Sotheby's catalogues say 7,014.
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
To meet the SCCA requirement of at least 6,500 cars, Ford built 7,014 Boss 302s in 1970, 514 more than needed. A contemporary Car and Driver test recorded the quarter-mile in 14.9 s at 93.4 mph. Engines received smaller valves for better drivability, with horsepower unchanged at 290.
In racing, the Bud Moore-prepared Mustang of Parnelli Jones took the 1970 SCCA Trans-Am championship for Ford. One catalogued 1970 car listed a base price of $3,720 before options such as the Shaker hood scoop, rear window slats, rear spoiler, close-ratio four-speed and 3.91 Traction-Lok differential.
