The BluePrint Engines GM LS Compatible 376 C.I. Builder Series Engine & TKX 5-Speed Manual Transmission Package delivers modern LS performance with the driver engagement of a manual gearbox in one complete turnkey drivetrain package. Producing 530 horsepower and 495 ft.-lbs. of torque, this combination is designed for pro touring builds, restomods, muscle cars, street rods, and custom LS swap projects that demand responsive performance and everyday drivability.

Built around BluePrint's high-strength LSX-style cast iron block, the 376 C.I. engine features BluePrint aluminum cylinder heads, hypereutectic pistons, forged connecting rods, a nodular iron crankshaft, and a hydraulic roller camshaft engineered for strong mid-range torque and impressive top-end power. Fuel and ignition are managed by the included Holley Terminator X Max Gen IV EFI System, complete with ECU, engine harness, sensors, and calibration for simplified installation and outstanding drivability.

The package is paired with the legendary TREMEC TKX 5-Speed Manual Transmission, providing smooth shifting, improved torque capacity, and overdrive cruising for modern street performance. Because this Standard Edition Builder Series package is intended for custom installations, no front accessory drive is included, allowing builders to select the pulley system that best fits their application.

Whether you're building a Camaro, Firebird, Corvette, Chevelle, Nova, C10, G-Body, or custom street rod, the BLS3763TKX offers BluePrint reliability with the control and enjoyment that only a manual transmission can provide.
