BluePrint Engines 376 c.i. GM LS Compatible Builder Series - Standard Edition - Supercharged - 4L80E Automatic Transmission. (PART #BPE-3769SCT4L8)

The BluePrint Engines GM LS Compatible 376ci powerplant, paired with the formidable Magnuson TVS 2650 Supercharger, is a testament to modern performance engineering. This robust setup is anchored by the Holley Terminator X Max Gen IV ECU and harness system, delivering precise fuel and spark control for maximum efficiency and power. The integrated EFI system, complete with high-flow fuel injectors and rail, ensures consistent delivery under demanding conditions.

Supporting components like the oil pan, coil packs, spark plugs and wires, water pump, and harmonic balancer are all meticulously selected to withstand high-output stress and maintain reliability. Mated to a heavy-duty 4L80E four-speed automatic transmission, this combination offers seamless power delivery and durability, making it an ideal choice for high-performance street builds or track-ready machines.

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.
• BluePrint Engines Recommends Air Intake Kit BPPLS01013 to ensure correct MAF calculations and Dyno calibration are maintained with the above ECU / tuning.
• Your engine requires pre-lubing before startup. Your engine has been dyno tested, but it does require additional preventative maintenance before initial startup. Fill oil filter and oil pan to recommended capacity. Remove spark plugs and proceed to crank engine over with starter until oil pressure is visible on manual gauge. Reinstall spark plugs and proceed with initial startup. It is critical that you read and follow the installation instructions in the installation guide.
• Not for use in pollution-controlled vehicles.
