Product Description:

The BluePrint Engines GM LS Compatible 427 c.i. Pro-Series Engine and T56 Manual Transmission Package combines the exhilarating performance of a supercharged LS engine with the driver-focused control of a six-speed manual transmission. Designed for Pro-Touring builds, restomods, muscle cars, and custom LS swaps, this Standard Edition Builder Series package features an 800 horsepower 427 c.i. Pro-Series LS-compatible engine, Gen 6 3.0L Whipple Supercharger, T56 six-speed manual transmission, Natural Pulley Kit, and Holley Terminator X Max EFI System for a complete turnkey drivetrain solution.

Built around a heavy-duty LS-compatible cast iron block, the 427 c.i. Pro-Series engine utilizes premium aluminum cylinder heads, a forged rotating assembly, hydraulic roller camshaft, and a 9.5:1 compression ratio optimized for forced induction. The Gen 6 3.0L Whipple twin-screw supercharger delivers immediate throttle response, exceptional airflow, and impressive torque across the entire RPM range.

The included Holley Terminator X Max Gen IV EFI System provides complete engine management through a BluePrint-calibrated ECU and wiring harness. Combined with the legendary T56 six-speed manual transmission, this package delivers outstanding durability, smooth shifting, and exceptional performance for street or track use.

Finished with a Natural Pulley Kit, this package offers a clean factory-inspired appearance while complementing the polished finish of the supercharger and accessory drive.
