BluePrint Engines GM LS Compatible Pro Series 427 C.I. Base Dressed, Supercharged (PART #BPE-PSLS4279SCT)

The LS-compatible platform is the undisputed king of street machines, and this BluePrint Engines 427 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.
