BluePrint Engines B426SCTK4L8 Hemi 426/4L80E, Supercharged, Pol.

This BluePrint Engines Gen III HEMI crate engine paired with a complete 4L80E four-speed automatic transmission is a turnkey, high-performance powerhouse, producing an incredible 872 horsepower and 764 ft-lbs. of torque with a pump-gas-friendly 10.48:1 compression ratio. Built with premium internals—including a forged crank, forged pistons, and a hydraulic roller cam—and topped with Gen III HEMI Apache aluminum cylinder heads, this engine is force-fed by a Whipple 3.0L supercharger and Hellcat throttle body, backed by a dedicated supercharger coolant reservoir for consistent performance. Engine management is handled by a Holley Terminator ECU controller kit and wiring harness, providing precise control over fuel injection and ignition. Key components like spark plugs, coils, timing cover, valve covers, harmonic balancer, and a muscle car-style mid-sump oil pan make this engine swap-ready. The polished front accessory drive system includes a high-flow water pump, Type II power steering pump with remote reservoir, 140-amp 1-wire alternator, and a 7B10 peanut-style A/C compressor, blending function and show-quality looks. With the strength and overdrive capability of the 4L80E transmission, this package is ideal for high-powered street machines demanding modern reliability and supercharged performance.
