Buy BluePrint PSLS3760CTFK 376CI Dressed LS3 Engine Online
BluePrint Engines PSLS3760CTFK is a 376ci (6.2L) LS3-based, deluxe dressed crate engine designed for high-performance swaps and turnkey installations. Built around a new GM aluminum block with a 6-bolt main and 1-piece rear main seal, it delivers an advertised 530 hp and 495 lb-ft with a 10.7:1 compression ratio. LS3-style aluminum cylinder heads and a hydraulic summit racing 5.3 crate motor roller cam (.612/.585 lift, 225/238 duration @ .050, 113 LSA) provide strong street power and crisp throttle response.
The package arrives dressed with a polished front accessory drive, including water pump, harmonic balancer, alternator, power steering pump, A/C provisions, belts, and ls3 engine for sale pulleys, plus a loaded intake with fuel rails/injectors, drive-by-wire throttle body, coils, plugs, and wires. Uses 58x crank and 4x cam sensors; controller kit required. Internally balanced rotating assembly ls3 crate engine features a nodular iron crankshaft, forged rods, and hypereutectic blueprint ls3 engine pistons for durability. Recommended 91-octane fuel and 2200+ stall converter; dyno sheet included for verification.

Benefits (Why This Engine)
- Big, proven power in a street-friendly combo: 530 HP and 495 lb‑ft is a strong step-up for swaps and restomods while keeping LS drivability potential.
- Dressed to save time and guesswork: Having intake/EFI hardware plus a complete front accessory drive already selected and installed reduces parts hunting and bracket/pulley mismatch issues.
- Durable foundation: A cast-iron LS-based block and robust rotating assembly support blueprint engines ls3 sustained use and high-load applications.
- Modern throttle response & drivability (EFI retrofit): With the right ECU/controller, you get easier starting, smoother idle, and better everyday behavior than carb-only setups.
- Clean, premium appearance: Polished pulleys upgrade the engine bay look without needing aftermarket dress-up parts.
- Swap-friendly internal balance: Internal balancing typically simplifies flywheel/flexplate selection (non-weighted) compared to externally balanced setups.
