BluePrint Engines BLS3769SCTKB4L8 Details

The BluePrint Engines GM LS Compatible 376ci is a masterclass in high-performance durability, engineered to deliver a staggering 700 horsepower and 640 lb-ft of torque with unwavering reliability. At the heart of this beast lies the Magnuson TVS 2650 Supercharger, providing instant, efficient boost and relentless power across the RPM range. The Holley Terminator X Max Gen IV ECU and harness system ensures precise engine management, while the advanced EFI system—complete with high-flow fuel injectors and rail—maintains optimal combustion under extreme conditions. Every supporting component, from the oil pan and coil packs to the spark plugs, wires, water pump, and harmonic balancer, is built to withstand the rigors of high-output operation. Paired with the bulletproof 4L80E automatic transmission, this setup offers smooth, torque-rich shifts that handle the power with ease. Finished with the Holley Black Front pulley kit, this configuration is not only robust and performance-driven—it’s a statement of engineering excellence.
