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.
