Description
The BluePrint Builder Series LS427/585HP Standard Edition EFI crate engine and T56 transmission combos take the guesswork out of matching up an engine and transmission for your ride. Featuring a fuel injected Chevy LS small block-compatible 427 (c.i.d.) engine that produces 585 hp, this standard edition builder series includes a polished (or black) pulley kit and T56 manual transmission. The BluePrint aluminum cylinder heads help produce a nice 11.0:1 compression ratio, with assistance from the hydraulic roller camshaft, forged pistons, and forged steel crankshaft. Altogether, this assembly produces 520 lbs.-ft. of torque. When you need or want a new LS powertrain for your ride, go with the authority in crate engines and their BluePrint Builder Series LS427/585HP Standard Edition EFI crate engine and T56 trans combos.

Important Notes: This engine requires a non-weighted flex plate/flywheel. Recommended Fuel: 91 Octane. The front accessory drive on this engine fits many vehicles, however it is the customer responsibility to accurately measure and confirm fitment. Note this is a low-profile design, but things such as power steering hoses, alternator wiring, and additional fittings/fabrication may be required on some vehicles. BluePrint Engines recommends a 2200+ RPM stall converter. Retro fit oil pan will fit most 1955-1995 GM front engine, RWD, V8 cars. Not for use in pollution-controlled vehicles or in dry sump applications. The LS controller package is for engine control only. Does not contain any transmission or body control. The ECU comes with calibration that is optimal for our engine, however, please note that vehicle parameters such as gearing, tire size, vehicle weight, air intake, headers, etc. may necessitate additional tuning once installed into your specific vehicle. The ECU is unlocked for further refinement at your local dyno shop if required.
BluePrint Engines recommends their air intake kit (BPPLS01013) to ensure correct MAF calculations and Dyno calibration are maintained with the provided ECU/tuning.
