Overview

The Blueprint Engines 376 cubic inch Pro Series crate engine is a dyno-tested, turnkey powerplant that delivers 530 horsepower and 495 lb-ft of torque or 549 HP / 469 FT LBS. It is an ideal match for Holley’s Terminator X Max 550-931 EFI system. This LSX-based engine features a BluePrint Engines High Strength cast iron (LSX Style) block with reinforced internals, including a nodular iron crankshaft, forged rods, and hypereutectic pistons—all internally balanced for durability and long-term performance. It is paired with LS3-style aluminum heads and a .612 Intake / .585 Exhaust Lift hydraulic roller cam. The 10.7:1 compression ratio offers strong street and strip capability. 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. It includes a pre-installed intake manifold, injectors, throttle body, water pump, and an easy to mount DBW pedal, making it swap-ready. It is backed by a 30-month/50,000-mile warranty.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
