Ford Performance Parts integrates decades of proven performance on the street and at the track into its popular line of bare engine blocks. From legendary Boss 302 small block to the modern 2.3L EcoBoost engine, Ford bare blocks are built using the latest technologies and machining methods to ensure superior strength, lasting durability, and performance.
There are a variety of reasons you might consider a bare engine block over a fully equipped, drop-in crate engine for your project. Here are a few of the most common:
A crate engine does not afford you the level of customization you desire.
You want to build your powerplant in the most cost-effective way possible.
You want to replace a worn or damaged engine block, while retaining as many existing components as you can.
You simply want the experience of building a complete engine on your own.
Whatever your reason for choosing a bare engine block, Ford Performance Parts has a variety of V8 and turbocharged L4 block options to suit your needs.
Ford Performance Parts Boss 302 Engine Blocks—Designed as a replacement for Boss 302 and 351 blocks, Ford Performance Parts Boss 302 bare blocks combine classic design with the benefits of modern manufacturing techniques. Each block is cast from diesel-grade iron with siamesed bores and thick cylinder walls and decks. They are available in standard and big bore versions that support engine sizes up to 363 c.i.d.
Ford Performance Parts 351 Aluminum Windsor Engine Blocks—Featuring cast iron sleeves and available in 9.2- or 9.5-inch deck heights, 351 aluminum Windsor engine blocks employs a user-friendly design that is compatible with conventional Windsor components like cams, timing chains, timing chain covers, oil pans, and oil pumps.

Ford Performance Parts 2018 Gen 3 5.0L Coyote Production Cylinder Blocks—Start your build with the same Gen 3 5.0L Coyote cylinder block that can be found on the 2018 Mustang GT 5.0L. Compared with previous GT aluminum blocks, the Gen 3 version offers better durability, heat transfer, friction reduction, and weight savings thanks to a plasma-transferred wire arc spray weld liner coating.
Ford Performance Parts 5.2L Gen 3 Coyote Aluminum Engine Blocks—Found in the Shelby GT350 Mustang, the 5.2L Gen 3 Coyote aluminum engine block offers extreme power potential in a 113-lb. package. All features of the block, including the head deck and crank bore, are finish-machined.
