The 1969-70 Boss 302 Mustang Facts

Here's a performance feature that's standard on the BOSS yet not even available on some Trans-AM competitors. a functional front spoiler. This unit helps to keep air out from under the car, make it more stable, cut drag and even increase gas mileage. It's effective at speeds in excess of 40 miles per hour and a real plus when operating on the track

Ford's fully-synchronized four-speed manual transmission is mandatory on the BOSS 302. Designed to provide the ultimate in driving flexibility and performance, this transmission's four ratios are properly spaced to fit the 302 HO power curve. Its rugged construction allows extended operation in any ratio, such as using third gear for cruising on hilly, winding roads. The console-mounted shift lever is indexed for fast, sure shifting, lending itself to competition events. Fully-synchronized gears permit positive, split-second upshifts and downshifts at all reasonable engine speeds.

The BOSS is really the Boss on interiors. From the optional high backed bucket seats trimmed in cool "Comfortweave" knitted vinyl which one of the leading motor magazines calls "probably the most comfortable of any American car in 1969" down to the standard luxury nylon carpeting, the BOSS offers a choice of interiors that's unequaled in its field. With the deluxe interior decor group, simulated teakwood applique trims the instrument panel and optional console as well as the sports-styled "Rim-Blow" steering wheel to top off the unique "twin pod" dash arrangement of the BOSS.

Quick ratio steering makes handling the BOSS 302 a pleasure. The 16 to 1 steering ratio and 3.74 turns lock-to-lock gives the driver true sports car response. an exceptional attribute for the twisting Trans-Am courses. The "Rim-Blow" 3-spoke deluxe steering wheel is available as an option.

An option certain to be popular with the all-out enthusiast are these practical "Sport Slats" on the rear backlite. Functional. they improve the already excellent airflow characteristics of the SportsRoof. Practical . . . they provide that often desired shade for any rear seat passenger without blocking rear visibility of the driver.


Another "plus" for the BOSS 302 is this optional and functional adjustable rear deck spoiler. Designed to take over where the front spoiler leaves off, the rear deck spoiler adds to the stability and handling of the BOSS, especially during competitive events.

Standard equipment calls for F60 x 15 fiberglass belted tires mounted onto 7-inch rim argent-finish "Magnum 500" steel wheels with bright trim rings. The wheels are 1-inch wider than the F70's so even the wheel opening flange had to be flaired to get them on. And, for the real buff, there's a set of chrome "Magnum 500" steel wheels to give an added touch of performance appearance. Besides their sharp, exciting, sporty appearance, they're completely functional and rarin' to roll.

The BOSS' mandatory front disc brakes have a one-piece cast-iron disc with a floating caliper straddling the disc and an inboard splash shield. The ventilated cast-iron disc provides exceptional cooling and water dissipation. The dual-diaphragm power brake booster helps to reduce system reaction time for faster and better braking control. The front disc / rear drum power brake system requires up to 40% less pedal pressure than the manual system. Increased fade resistance, even after repeated stops, improved recovery from water, and the ease of servicing disc brakes make them ideal for the sportsman driver while providing maximum braking power.


The special version of the 302 cid engine to be installed in the BOSS 302 is the 5 liter F.I.A. formula engine. To achieve the desired high output and high rpm capabilities, this engine features completely new cylinder heads with high turbulence polyangle wedge combustion chambers. The valves have been canted to favor gas flow for free breathing efficiency. Canting the valves also allows more push rod clearance for the inlet ports and provides head space for a substantial increase in valve size. Intake valves are 2.23 inches in diameter. Solid tappets allow the use of a quicker cam and extremely precise valve timing. The forged steel crankshaft is statically balanced and dynamically balanced electronically while running under its own power. To with-stand severe high speed stress, the oversize forged bearing caps use four bolts in place of two. Extra strength forged connecting rods, bearing caps and rod bolts are used along with forged aluminum pistons. A high capacity double breaker ignition and a four barrel 780 CFM Holley carburetor are also a part of the 302 HO power plant.
