The Chevy 454 Crate Engine big-block V8 is the engine that defined heavy-duty American performance and work capability for a generation — available in everything from the Chevelle SS 454 muscle car to the C/K heavy half-ton and 3/4-ton work trucks that needed maximum torque for maximum loads. This used Chevy 454 engine is sourced from low-mileage donor vehicles and inspected before shipment. Whether you are restoring a muscle car, rebuilding a work truck, or executing a big-block powered project build, this is the factory-built GM 454 that belongs in it.

The 454 Crate Engine is a legendary 7.4L Chevrolet big block V8 designed for maximum power, torque, and durability. Producing impressive horsepower with massive low-end torque, the Chevy 454 engine has long been a favorite for muscle cars, trucks, hot rods, and custom builds. Its heavy-duty cast-iron block and performance cylinder heads ensure strength and long-lasting reliability.
Available as both a 454 replacement engine and high-performance LSX 454 crate engine, this motor delivers flexibility for restoration projects and modern performance upgrades. With broad aftermarket support and GM engineering, the 454 Chevy engine remains one of the most trusted big block engines ever built. Whether you’re upgrading a classic, replacing a worn-out block, or building a custom street machine, the Chevrolet 454 crate engine provides unmatched power and dependability.
454 fitment depends on your specific application, model year, and fuel system. The early high-performance 454 variants (LS5, LS6) are different from the emissions-era fuel-injected TBI and Vortec 7400 L29 production variants in fuel system, compression ratio, and cylinder head configuration. Our application review process confirms the correct 454 variant for your specific vehicle or build before it ships.
For builders and restorers comparing a used engine against a remanufactured engine or new crate engine for the 454, the used OEM route offers a factory-original alternative. A used Chevy 454 engine from a verified donor gives you the original big-block displacement and cast-iron torque character as an OEM engine assembly — the actual factory casting numbers, the factory compression, the factory bore and stroke. Unlike a remanufactured engine rebuilt from a core, this used engine preserves the original factory identity of the 454 that restoration buyers specifically seek.
Every used Chevy 454 engine ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. These are genuine GM OEM engines, and we stand behind every unit.
