SBC 383 Crate Engine 445HP

The SBC 383 Crate Engine 445HP from Blueprint Engines is a complete, ready-to-install small-block Chevy powerplant engineered for builders and enthusiasts seeking significant displacement and horsepower without the complexity of a full engine build. This crate engine delivers the cubic-inch advantage of a 383 with modern reliability, making it the ideal foundation for street rods, muscle car restorations, trucks, and high-performance applications.

Built on a proven small-block Chevy architecture, the 383 cubic-inch displacement achieves its 445 horsepower rating through optimized bore and stroke geometry that increases total engine volume beyond the standard 350 platform. The long-block configuration includes premium internal components, a balanced crankshaft, forged pistons, and a cam profile tuned for broad torque delivery across the RPM band.

Blueprint Engines' quality control and assembly standards ensure each engine arrives fully inspected, pressurized, and ready for fuel system, ignition, and exhaust integration into your vehicle. Builders and hot rodders benefit most from this crate engine's simplicity—no machine work, no guesswork, and no extended build timelines. The SBC 383 accepts standard Chevy small-block accessories, intake manifolds, carburetor or EFI systems, water pump, and alternator.
