Complete Engines & Crate Engines

Complete engines and crate engines provide a fully assembled, ready-to-install long block or turn-key powertrain for engine swaps, replacements, and new builds. From remanufactured stock engines to high-performance crate engines with upgraded internals, a complete engine saves the time and complexity of sourcing and assembling individual components.

OneFastShop carries complete engines including crate engines, long block assemblies, short block assemblies, remanufactured engines, and performance-built engines for popular automotive platforms.

Every engine at OneFastShop ships brand-new or professionally remanufactured with manufacturer warranty coverage. Whether you're replacing a blown motor, building a swap project, or dropping in a performance crate engine, OneFastShop has the powertrain. Shop the full engines collection today.
