This long block engine delivers a solid 375 horsepower and 460 ft-lbs. of torque with a reliable 9.8:1 compression ratio, making it a strong foundation for street performance or muscle car builds. It features durable Magnum cast iron heads, a classic flat tappet cam, and a cast crankshaft paired with forged pistons for added strength and longevity. Included components like the valve covers, oil pan, and timing cover make this a ready-to-build long block that offers the perfect balance of old-school muscle and dependable power. This engine comes with Magnum heads so it will require a Magnum Intake Manifold (BPP7577).
