Overview:

This BluePrint Engines Gen III HEMI crate engine with TKX five-speed transmission package is a complete, high-performance drivetrain solution engineered for street and pro-touring builds. Delivering 610 horsepower and 525 ft-lbs. of torque with a 10.48:1 compression ratio, it’s built with premium internals—including a forged crank, forged pistons, and a hydraulic roller cam—for durability and power under real-world driving conditions. Gen III HEMI Apache aluminum cylinder heads and a fabricated intake manifold ensure excellent airflow, while modern throttle body fuel injection and a Holley Terminator ECU controller kit with wiring harness provide precise tuning and drivability.

The package is complemented by a fully assembled TKX five-speed transmission, including a flywheel, for smooth shifting and high-performance street use. A polished/black front accessory drive system adds function and style, with a water pump, Type II power steering pump and remote reservoir, 140-amp 1-wire alternator, and a compact 7B10 peanut-style A/C compressor. A muscle car-style mid-sump oil pan makes this setup swap-friendly for classic applications. Whether you're building a resto-mod, a weekend cruiser, or a street-strip machine, this package delivers turn-key modern HEMI power with the reliability and performance BluePrint Engines is known for.
