California Proposition 65 Warning Overview:
The Blueprint Engines 427cubic inch Pro Series crate engine is a dyno-tested, turnkey powerplant that delivers 605 horsepower and 565 lb-ft of torque, making it an ideal match for Holley’s Terminator X Max 550-931 EFI system. This engine features a BluePrint Engines High Strength cast iron (LSX Style) block with reinforced internals, steel crankshaft, forged rods, and forged pistons, all internally balanced for durability and long-term performance. Paired with LS3-style aluminum heads and a .624 Intake / .624 Exhaust Lift and 239 Intake / 255 Exhaust Duration @ .050 - 114° LSA hydraulic roller cam, the 11:1 compression ratio offers strong street and strip capability. The Terminator X Max ECU included in the kit integrates seamlessly with this engine’s 58x crank and 4x cam sensor setup, providing plug-and-play functionality with drive-by-wire throttle, coil packs, and EV6-style fuel injectors already installed. The ECU’s self-learning fuel map ensures easy startup and quick adaptation to the engine’s fueling needs without complex tuning, while also enabling expandability for nitrous, boost control, or electric fan integration via CAN or I/O modules like Holley’s 554-165. With included accessories like a pre-installed intake manifold, injectors, throttle body, water pump, and an easy to mount DBW pedal, this engine is truly swap-ready. Whether for a restomod, pro-touring build, or a street performance application, the combination of a dyno-certified engine and the advanced control of the Terminator X Max offers unmatched reliability, tunability, and future upgrade potential—all backed by a 30-month/50,000-mile warranty.
