    Overview: 

    The LS-compatible platform is the undisputed king of street machines, and this BluePrint Engines 376 C.I. Pro Series LS compatible powerhouse proves exactly why. Built to dominate, this base-dressed beast unleashes a jaw-dropping 700 horsepower and 640 ft-lbs of torque, this base dressed beast packs a 9.5:1 thanks to a combination of BluePrint aluminum heads, hydraulic roller cam, forged pistons, and a nodular iron crankshaft, all securely anchored in a high-strength LSX-style block. Controlling this build is Holley’s Terminator X EFI system preloaded with a base tuning map tailored for this engine. Real-Time Fuel Map Learning simplifies tuning by dynamically adjusting fuel delivery, while the Bosch LSU 4.9 wideband sensor enables precise AFR monitoring and advanced closed-loop tuning. With eight high-impedance injector drivers, it’s compatible with both stock LS and Holley EFI injectors. An integrated 1-bar MAP sensor supports naturally aspirated or mild nitrous setups, with optional harnessing for higher-bar sensors. Four configurable inputs and two outputs give you control over accessories like electric fans, boost solenoids, or nitrous. Fine-tune via free PC software or on-the-fly with the included 3.5" touchscreen handheld, complete with setup wizard, real-time gauges, and data logging.
