BBC EFI 454 Crate Engine 490 HP - 479 Lbs Torque

The Blueprint Engines BBC EFI 454 Crate Engine delivers 490 horsepower and 479 pounds of torque in a drop-in-ready package designed for serious performance builds. This big-block Chevy EFI crate engine combines modern fuel injection with classic 454 cubic-inch displacement, eliminating the tuning complexity of carburetor conversion while maintaining the raw power that made the big-block platform legendary. Factory-matched EFI electronics and included pulleys make this engine ready for installation without extensive custom fabrication.

The 454 cubic-inch displacement produces substantial torque across the RPM band, critical for vehicles operating at highway speeds or under load. The 490 hp / 479 lb-ft combination represents the balance Blueprint Engines engineered into this platform—enough displacement to move weight efficiently without requiring extreme RPM or fuel octane. Electronic fuel injection provides cold-start reliability, improved throttle response, and consistent air-fuel ratios across operating conditions. The included pulleys ensure compatibility with standard serpentine belt systems, reducing assembly delays and compatibility questions.

This crate engine suits restoration projects, performance trucks, and specialty vehicle builds where modern reliability must complement classic displacement. At 808 pounds, the engine requires proper engine hoist equipment and structural support during installation. Builders working with older frames or custom fabrications should verify clearance using the 35.5 x 34 x 44-inch envelope. The drop-in-ready configuration reduces labor hours compared to traditional carbureted big-block swaps, making this option economical for shops and experienced fabricators alike.
