Story
Evidence summary
The 1970 Ford Mustang Boss 302 was Ford's factory Trans-Am homologation Mustang for buyers who wanted small-block balance, road-race hardware, and unmistakable Boss graphics. Ford and period-reference sources identify the car as a SportsRoof fastback powered by a G-code 302-cubic-inch Boss V8 rated at 290 gross horsepower and paired with a four-speed manual transmission.
The appeal is not just the displacement number. The Boss 302 package ties together the Ford small-block, Cleveland-style canted-valve cylinder heads, Holley four-barrel carburetion, competition suspension, quick steering, front disc/rear drum brakes, Ford 9-inch axle choices, and the 1970-only visual package with bold side stripes and black hood treatment. That makes it a natural counterpart to the Camaro Z/28 and a key page for understanding the Trans-Am branch of the muscle-car era.
Production references do not agree on every count: one table lists 7,013 1970 Boss 302 fastbacks, while registry-derived references commonly use 7,014 and provide color estimates. This page keeps those figures source-attributed instead of flattening them into one unsourced number. For authenticity checks, the high-value signals are the G-code VIN, SportsRoof body context, four-speed-only configuration, Boss-specific engine architecture, build sheet or equivalent paperwork, and date-correct drivetrain evidence.
