426ci Crate Engine and Transmission Package

This BluePrint Engines B426KBTKX represents a comprehensive, high-performance drivetrain solution, integrating a powerful 426 cubic inch HEMI-compatible crate engine with a TKX five-speed manual transmission. Engineered for demanding street and pro-touring builds, this package boasts 610 horsepower and 525 ft-lbs. of torque. At its core is a NEW "BGE" Hellcat Engine Block, complemented by a forged steel crankshaft with a 4.050" stroke, forged 6.125" connecting rods, and forged pistons, all internally balanced for smooth operation. The engine features Gen III Hemi Apache aluminum cylinder heads with 73cc chambers and 2.140" intake/1.650" exhaust valves, paired with a hydraulic roller camshaft offering .614" lift and 231°/255° duration at .050" lift with a 115.5° LSA. Modern drivability is achieved through throttle body fuel injection managed by a Holley Terminator ECU controller kit, requiring 91+ octane fuel. The accompanying TKX five-speed transmission comes fully assembled with a flywheel, McLeod Super Street Pro Twin Disc Clutch, and hydraulic throw-out bearing. A black front accessory drive system includes a water pump, Type II power steering pump with reservoir, a 140-amp alternator, and a compact A/C compressor. A muscle car-style mid-sump oil pan is incorporated for enhanced swap compatibility in classic vehicles. Key specifications include a 10.48:1 compression ratio and a one-piece rear main seal. The engine incorporates modern features such as a 2013+ 58X reluctor wheel, 2009+ crankshaft spacing, and a 2009+ car timing cover, with VVT locked out and MDS eliminated. BluePrint Engines ensures quality through meticulous balancing and dyno testing of every crate engine, backed by a standard warranty of 30 months or 50,000 miles (parts and labor). Installation guides and recommended fluids are available for proper setup and maintenance.
