Ford Racing BOSS 351 Cylinder Block 9.2 Deck Big Bore

If you're building a serious Ford V8, the Ford Racing BOSS 351 Cylinder Block is a solid place to start. This is a 9.2-inch deck height, big bore block designed for high-performance 351 cubic inch engine builds. It's built to handle significant power, whether you're planning for the track or just want a powerful street machine. The BOSS block has a proven track record, used worldwide in demanding applications.

Ford Performance casts and machines these blocks to high standards right here in the USA. It's designed to work with the original 302 and 351 Windsor block patterns, retaining features like the clutch cross shaft pivot hole, original oil filter location, original motor mount bosses, and the original bell housing pattern. This makes it a lot easier to integrate into your existing chassis and drivetrain. The block has a 4.185-inch bore capacity, finished at 4.12 inches, and is intended for specific Ford Performance cylinder heads like the M-6049-X306, X307, C3, D3, or Z304DA. You'll need special length 1/2-inch head bolts or head studs for installation.

This block is approximately 195 lbs and is designed to work with a factory oil pan, though it requires a custom oil pick-up tube, like the M-6622-BOSS302. It offers great value as the foundation for your next big bore engine project.
