BluePrint Engines Chevy LS 376 C.I.D. 530 HP EFI LS3-Style Long Block Crate Engine — PSLS3760CTFKB
The LS3 crate engine that ends the search — 530 HP, iron block, Terminator X EFI, turn-key. BluePrint Engines’ Pro Series 376 is the LS3-style package builders actually want: a cast iron block (the boost-ready choice), BluePrint LS3 aluminum heads, a hydraulic roller cam and a calibrated Holley Terminator X Max EFI system — dyno-tested at 530 horsepower and 495 lb-ft before it ships. Everything from the intake to the black accessory drive arrives installed. Crated and shipped fast across Europe from NH Race Engine.
Why Choose the BluePrint PSLS3760CTFKB LS3 Crate Engine?
LS swaps live and die by three things: power claims you can’t verify, EFI setups that fight you for months, and aluminum blocks that limit boost ambitions. The PSLS3760CTFKB answers all three: every engine is dyno-tested with the actual installed components (your dyno sheet ships in the crate), the Holley Terminator X Max is calibrated for this exact cam and displacement out of the box, and the cast iron block laughs at the turbo and supercharger plans most LS3 buyers secretly have. 10.7:1 compression runs happily on European premium pump fuel.
BluePrint Engines is America’s specialist crate builder — and the Pro Series is their flagship line, backed by the brand’s 30-month/50,000-mile warranty. This is the LS3 crate engine for buyers who want maximum power with minimum drama: calibrated EFI, installed accessory drive, and documentation for every claim.

Frequently Asked Questions
Does the Terminator X really come calibrated for this engine?
Yes — BluePrint supplies the Holley Terminator X Max pre-loaded with a base calibration for this exact cam, displacement and compression. It self-learns from there as you drive. Most engines run perfectly from the first start; fine adjustments, if wanted, are done from the handheld or a laptop.
Is the iron block a disadvantage versus the aluminum LS3?
Only on a scale. For swaps and boosted builds the iron block is actually preferred: thicker cylinder walls handle boost, the block is cheaper to replace if something goes wrong, and 25 kg is rarely felt in a truck or muscle car. Road racers and weight-obsessed builds should consider the PSLS3763 aluminum version instead.
What fuel system does it need?
A pump capable of 58+ PSI — an EFI-rated in-tank pump or Holley’s inline booster. Everything else (ECU, harness, sensors, wideband) is included. We stock EFI-ready tanks, pumps and line kits for classic chassis.
What transmission bolts up?
Any LS-pattern transmission: 4L60E/4L80E, T56/T56 Magnum, TR6060, or TH400 with an LS bellhousing. The Terminator X Max controls 4L60E/4L80E transmissions natively — no separate trans controller needed.
Is the warranty valid in Europe?
Yes — BluePrint’s 30-month/50,000-mile warranty is supported in Europe through NH Race Engine directly. No transatlantic shipping for claims. Full terms ship with your engine.
