Ford Racing Engine Blocks: Race-Proven Foundations for Every Ford Build
When it comes to building serious Ford power, the engine block is where everything starts. Ford Racing — also known as Ford Performance Parts — brings decades of motorsports engineering directly to enthusiasts through a lineup of engine blocks that span the full spectrum of Ford's iconic powerplants: from the legendary small-block Boss 302 and 351 Windsor to the modern Coyote and turbocharged EcoBoost family.
What separates Ford Racing blocks from aftermarket alternatives is pedigree. Ford Performance Parts integrates decades of proven performance on the street and at the track into its popular line of bare engine blocks — from the legendary Boss 302 small block to the modern 2.3L EcoBoost, built using the latest technologies and machining methods to ensure superior strength, lasting durability, and performance.
The Boss 302 Block: A Small-Block Legend, Re-Engineered
Perhaps the most celebrated offering in the Ford Racing engine block lineup is the Boss 302. Ford Performance engineers designed the replacement for the legendary Boss 302 and 351 blocks using the latest technology and manufacturing techniques from both the production and racing worlds. Cast from diesel-grade iron with siamesed bores, thick cylinder walls and decks, Boss block strength is far superior to any Ford production block.
Available in standard and Big Bore versions with an 8.2" deck height, the Boss 302 is designed with optimized cylinder wall length for stroker applications up to 3.5" with no grinding or clearancing, and features a NASCAR-inspired front oil feed on both lifter galleys. The Boss 302 Big Bore block supports engine sizes up to 363 cubic inches. It has proven performance — used in Ford Performance sealed 347cid race engines and Ford Performance high-performance crate engines, a proven winner with thousands of laps to demonstrate durability.
By preserving many of the dimensions and features from the original 289–351 blocks, the Boss blocks are compatible as replacements for virtually any vehicle that used a Windsor-style engine — making them equally at home in a Mustang restoration, a kit car, or a dedicated track build.
Coyote, 7.3L, and Modern Modular Blocks
Ford Racing's block catalog extends well beyond the classic small-block. The Gen 3 5.0L Coyote production cylinder block — the same one found in the 2018 Mustang GT 5.0L — offers better durability, heat transfer, friction reduction, and weight savings thanks to a plasma-transferred wire arc spray weld liner coating. The 5.2L Gen 3 Coyote aluminum engine block, found in the Shelby GT350 Mustang, offers extreme power potential in a lightweight package. Racers looking for the ultimate in durability can also consider the cast iron Coyote race block, purpose-built for high-output applications.
The 2.3L EcoBoost Mustang cylinder block offers plenty of performance potential in a turbocharged build and includes plugs, dowels, and other production hardware. For big-block fans, Ford Racing also offers the 460 Siamese Big Bore cylinder block and the 7.3L Gas Engine Race Block (M-6010-SD73R), extending the lineup's reach to truck and diesel-displacement platforms.
Formula Ford and Lotus Heritage Blocks
Ford Racing's commitment to grassroots motorsports is reflected in its Formula Ford offerings. The legendary Formula Ford Kent block has been reborn with an all-new iron casting that is stronger than the original, designed to replace production 1.6L Kent blocks for SCCA Formula Ford competition. Using original blueprints and modern techniques perfected over many years casting high-performance engine blocks, Ford has improved the original Kent engine blocks for strength and reliability.
