Ford Racing 347 Cubic inch BOSS Short Block

When you're ready to build a serious performance engine for your 1985-1995 Ford Mustang, this Ford Racing 347 cubic inch BOSS short block is the perfect place to start. It's the foundation for a powerful 8.2-inch deck engine, ideal for vintage muscle cars, street rods, or your Fox Body or Late Model Mustang. This is the same robust short block used in Ford Racing's own 347 sealed racing crate engines, so you know it's built for serious performance.

Inside this short block, you'll find nothing but top-tier components. It features a forged crankshaft for strength and durability, paired with forged I-beam connecting rods that use floating piston pins for improved reliability under stress. The heart of this assembly is the legendary BOSS 302 block, known for its solid construction and performance potential. This short block comes with all new parts, ready for you to add your preferred cylinder heads, camshaft, intake manifold, and oil pan to complete your custom build.

Please be aware that this part is designed and intended for competition use only. It is not street legal and should not be installed on a vehicle driven on public roads and highways, as this may violate emissions laws and regulations. It is also not CARB approved and cannot be shipped to California.
