Overview:

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.
