The BOSS 302 Mustang

Ford today announced at the Specialty Equipment Market Association (SEMA) show that it is reviving the legendary 5.0-liter 302 cubic inch V-8 engine for the aftermarket with a new line of BOSS 302 crate engines, which will go on sale in early 2007.

Making its debut in 1969, the original BOSS 302 powered a limited production Mustang model sold for two years, which was known as the BOSS 302. The car got its name from the legendary engine that powered the Mustang to a Sports Car Club of American Trans-Am series win in 1970.

“The original BOSS 302 was a race winning engine. Sharing the DNA from the original BOSS 302, the new BOSS 302 begins with a block designed with racing in mind from the beginning,” said Jamie Allison, manager, Ford Racing Performance Group. “Whether racing in a sealed engine class, building an all-out drag racing engine or looking for a street performer, the BOSS 302 block and engine family meets the needs of all Ford 302 enthusiasts at a price that is comparable to a performance-prepped stock 302.”

The new Ford Racing Performance Parts BOSS 302 line was conceived because there was an unmet need for engines built from a block stronger than original regular production 302 blocks but more affordable than full race-prepped blocks. The new BOSS 302 engine block features greater strength than most race blocks and offers a street-capable cooling system design, something that race specific blocks tend to sacrifice.



Despite its strength and capability, the new BOSS 302 line is surprisingly affordable because of its high volume production. And since it was designed within Ford Motor Company, the engine also benefits from the improved quality and durability that comes with a production type engine.

“The original BOSS 302 delivered less than 300 hp. Today, enthusiasts are making 500 hp street cars and they need a robust block. Race-specific blocks offer the strength required but cool poorly for street use and are very expensive for the average enthusiast,” says Allison.

Built from the all new BOSS 302 block, the BOSS crate engines feature performance and packaging that accommodate displacements from 302 to 363 cubic inches. Entry level engines feature the Ford Racing GT-40X Xtra Performance Turbo Swirl aluminum heads to retain stock exhaust locations and are rated at 340 and 345 hp. Higher performance versions include Ford Racing’s “Z”-head equipped 302 and 347 cubic inch engines rated between 360 and 450 hp, depending on configuration. The BOSS engine series is capped by a 500 hp 331 cubic inch engine that showcases the capability of the new block by breathing through all new ported Z-heads.

Features that separate the new BOSS 302 from its competition include:

- 4-bolt mains for lower-end stability at high power outputs
- High-tin 41,000 PSI tensile strength iron alloy for ultimate strength
- Nodular iron main caps for additional strength
- Screw-in freeze plugs for additional more strength and stability
- Front cross-over lifter oiling for high RPM valvetrain capability
- Siamese bores with specifically engineered drillings between cylinders for maximum wall stability and gasket sealing with street capable cooling performance


The suggested retail price for the BOSS 302 block is and affordable $1,759, with BOSS engines ranging from $4,650 to $10,000 for the 500 hp BOSS 331 cubic inch engines. The engines come with a 12 month/12,000 mile limited warranty.

Like the original Boss 302 that was engineered for Trans Am racing, the new BOSS 302 features trickle down performance from racing in the American Speed Association (ASA) Late Model circle track series. A sealed circle track version of a 347 cubic inch BOSS engine will be available both for ASA and NASCAR circle track racers in time for the 2007 season.

Debuting in four SEMA display vehicles, four premier car builders placed the new BOSS 302 in their 2006 show vehicles. All the builders chose to use a 302 cubic inch engine, staying true to the original namesake.

Featured builders are:

Dan Web – Award-winning hot rod creator is featuring a 390 hp BOSS engine in his 1933 Ford 3-window coupe.
Galpin Ford – Known for their “Galpinized” custom creations, they built a “retro-mod” 2007 Mustang featuring a 360 hp BOSS engine.
