BluePrint Engines Pro Series GM LS 376ci 700hp 4L80E Auto Crate Engine w/ 3.0 Whipple, Natural Pulley Kit, Terminator X EFI System

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 Gen 6 / 3.0 Whipple 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 Natural Front pulley kit, this configuration is not only robust and performance-driven—it’s a statement of engineering excellence.

• Please note, It is not necessary to run the Holley setup wizard, as this will erase the existing calibration loaded by BluePrint Engines. The ecu is fully unlocked and tunable for further adjustments once installed in customer vehicle.
• BluePrint Engines Recommends Air Intake Kit BPPLS01013 to ensure correct MAF calculations and Dyno calibration are maintained with the above ECU / tuning. 
• The front accessory drive on this engine fits many vehicles, however it is the customer responsibility to accurately measure and confirm fitment. Note this is a low-profile design, but things such as power steering hoses, alternator wiring, and additional fittings/fabrication may be required on some vehicles.
