Fuel Injector Clinic 775cc High Impedance Fuel Injector Set for Small Block Chevy Gen II Engines (IS300-0775H)
Support your high-performance Small Block Chevy Gen II build with the Fuel Injector Clinic IS300-0775H High Impedance Fuel Injector Set. This complete set of eight injectors flows 775cc/min (74 lb/hr) at 43.5 PSI (3 Bar) and 900cc/min (85 lb/hr) at the factory-style 58 PSI (4 Bar) fuel pressure. Utilizing the latest injector technology, these injectors deliver outstanding linearity, exceptional short pulse width repeatability, and excellent drivability while providing the fuel capacity needed for naturally aspirated, supercharged, turbocharged, and E85-capable performance combinations.
The IS300-0775H injector set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered and includes a comprehensive Data Match Sheet containing injector-specific flow and latency values for highly accurate ECU calibration. Plug and Play GM ECU calibration data is also available from Fuel Injector Clinic, making tuning easier on supported GM engine management systems.
This injector set includes PGTUSC8 injector connector pigtails for wiring harness conversion. If you prefer not to modify the factory wiring, optional PADPUtoJ8 Plug and Play adapters are available separately, allowing installation without cutting or soldering. Fuel Injector Clinic specifies this connector arrangement because it uses brand-new, unused injectors instead of remanufactured or core-program injectors, providing exceptional reliability and consistent long-term performance.
