BluePrint Engines 376 c.i. GM LS Compatible - Deluxe Dressed - Fuel Injected - Natural Pulley Kit (PART #BPE-S3763CTFK1)

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. 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.

Notes:

• 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.
• Holley terminator X MAX System supports transmission control but requires additional Transmission harness such as BPP558405.
• 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.
• BluePrint Engines Recommends Air Intake Kit BPPLS01013 to ensure correct MAF calculations and Dyno calibration are maintained with the above ECU / tuning.
