Rated at 610 horsepower and 525 ft-lbs of torque, this Gen 3 Hemi crate engine arrives fully dressed and dyno-tested, ready for drop-in installation in compatible Chrysler and Mopar applications. We stock this powerplant for builders who want proven performance without sourcing individual components. The street-friendly 10.48:1 compression ratio means pump gas compatibility, while the Holley Terminator controller provides precise fuel and timing management with full tuning capability.
Blueprint Engines builds this 426 on a new cast iron block with 4-bolt mains and a 4.090-inch bore. The rotating assembly features a forged steel crankshaft with 4.050-inch stroke, forged pistons, and 6.125-inch connecting rods, all internally balanced to within 2 grams. Apache aluminum cylinder heads flow through 2.140-inch intake and 1.650-inch exhaust valves with 73cc chambers. The hydraulic roller camshaft specs out at 0.610-inch intake lift and 0.611-inch exhaust lift with 231 and 255 degrees duration at 0.050-inch on a 113-degree lobe separation angle. Every engine ships with spark plugs, coils, timing cover, valve covers, harmonic balancer, and a muscle car style mid-sump swap oil pan included.
