HIGH-PERFORMANCE ENGINE. The BluePrint Engines ProSeries LS BPE Block 427 C.I. 625 HP Base Dressed Fuel Injected Crate Engine with Controller is a turnkey powerplant delivering 605 horsepower and 565 lb-ft of torque. Designed for performance enthusiasts needing a reliable and robust LS-based crate engine, it integrates modern EFI control for ease of use, superior drivability, and adaptability for further enhancements.
CONSTRUCTION AND APPEARANCE. This engine features a high-strength cast iron LSX-style block with increased deck thickness and strength webbing, reinforced internals including forged pistons, steel crankshaft with 4.125" stroke, and 6.125" rods, all internally balanced for longevity and smooth operation. It is equipped with BluePrint Engines LS3 aluminum cylinder heads with 69cc combustion chambers, 2.165" intake and 1.590" exhaust valves, and 259cc intake runners, combined with an 11:1 compression ratio and a hydraulic roller camshaft with .624 intake/exhaust lift, 239/255 duration @ .050, and 114° LSA for optimized valve timing. The finish includes OEM LS3 front and rear covers and an improved water jacket design for better cooling efficiency.
INSTALLATION. The base dressed engine includes a non-weighted flexplate requirement and a retrofit oil pan compatible with most 1955-1995 GM front-engine, rear-wheel-drive V8 applications. Installation requires standard mechanical knowledge with no major modifications or drilling needed for fitting the oil pan or accessories.
WARRANTY. The engine is backed by a 30-month or 50,000-mile transferable warranty covering parts and labor, supporting confidence in quality and durability.
APPLICATION. This crate engine is compatible with most GM LS-series swap applications and includes a self-learning Holley Terminator X Max Gen IV EFI system precalibrated by BluePrint Engines for simplified installation and tuning. The EFI system features real-time fuel map learning, Bosch LSU 4.9 wideband control, eight injector drivers, integrated MAP sensor, configurable inputs and outputs, and free PC tuning software. This engine includes the oil pan, windage tray, pickup screen, fuel injectors and rail, drive-by-wire throttle body, water pump, throttle pedal and sensors, GM plastic intake manifold, spark plugs and wires, harmonic balancer, and coil packs. It requires a non-weighted flexplate or flywheel and is not intended for use in pollution-controlled or dry sump lubrication applications.
