Ford Performance Boss 302 Cylinder Block.

The original Boss block proved itself time and time again. This new Boss 302 Block from Ford Performance features a new design and construction from the original 302 motors. For increased strength, Ford Performance, formerly Ford Racing, cast this new Boss block from diesel grade iron for a far superior block than any OE one. The dimensions of the block are the same as the original blocks, allowing it to fit into any vehicle that had a Windsor style engine.
