Ford Performance BOSS Small Block Crate Engine

The Ford Performance BOSS Small Block Crate Engine line combines legendary BOSS heritage with modern Ford Performance engineering in a complete, ready-to-install package built for serious Ford enthusiasts. Every engine in this lineup is founded on the iconic Ford Performance BOSS block — cast from diesel-grade iron with additional material in critical structural areas, including block decks and main webs — delivering strength and durability that surpasses any factory Ford block ever produced. The platform is purpose-built to handle serious power output on the street or at the track.

Every engine in this lineup is hand-assembled in the United States by Ford Performance using premium, all-new components throughout. The forged internal rotating assembly features SCAT® forged steel crankshafts, SCAT® forged connecting rods with ARP® bolts, forged Mahle® pistons with floating wrist pins, and Clevite® main and rod bearings. Ford Performance aluminum cylinder heads are paired with a hydraulic roller camshaft to deliver a broad, strong torque curve across the RPM range. An SFI-approved vibration damper is standard across the lineup for enhanced drivetrain protection.
