Ford Performance M-6010-BOSS302 is a diesel-grade iron engine block for compatible Windsor small-block Ford builds with an 8.2-inch deck. It is a bare block, not a complete engine.
- Rough bore supplied at 3.990-3.995 inches; maximum stated bore capacity is 4.125 inches
- Deck supplied at 8.200 inches plus 0.010-0.015 inch
- Splayed four-bolt center main caps; two-bolt first and fifth caps
- Machined for factory roller-lifter guides and retainer
Final machining and engine-build clearances must be established by the engine builder. Ford specifies special-length head fasteners and limits compatible cylinder heads; ordinary production 302/351W heads are not generally interchangeable with this block. Review the exact head list and installation sheet before ordering. A factory 1979-1995 Mustang oil pan requires the specified M-6622-BOSS302 pickup.
Ford designates this part for competition or off-highway use.
