Fuel Injector Clinic 1440cc High Impedance Fuel Injector Set for Small Block Chevy Gen II Engines (IS300-1440H)
Give your Small Block Chevy Gen II engine the fueling capacity needed for serious horsepower with the Fuel Injector Clinic IS300-1440H High Impedance Fuel Injector Set. This complete set of eight injectors flows 1440cc/min (140 lb/hr) at 43.5 PSI (3 Bar) and an impressive 1700cc/min (160 lb/hr) at the factory 58 PSI (4 Bar) fuel pressure. Positioned between Fuel Injector Clinic's proven 1200cc and 1650cc injectors, the IS300-1440H delivers the ideal balance of excellent street manners, exceptional drivability, and the fuel volume required for high-horsepower gasoline and E85-powered combinations.
Built using the latest high impedance injector technology, the IS300-1440H features exceptional linearity, outstanding short pulse width repeatability, and Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered and dynamically matched, with a detailed Data Match Sheet included to provide injector-specific flow and latency values for precise ECU calibration. This injector set includes PGTUSC8 injector pigtails, while optional PADPUtoJ8 Plug and Play adapters are available separately if you prefer an installation without cutting or soldering.
The 1440cc high impedance injector is compatible with virtually every popular performance fuel thanks to its stainless alloy valve construction. It is fully compatible with pump gasoline, E85, Q16, VP Import, FTW, MTBE oxygenated race fuels, and other racing fuels while maintaining excellent idle quality in street-driven vehicles. As with every Fuel Injector Clinic performance injector, these are brand-new injectors instead of remanufactured cores, providing exceptional reliability and long-term consistency.

Installation and Connector Information
This injector set requires changing the injector connectors on your engine wiring harness. The included PGTUSC8 pigtails can be soldered onto the factory harness, or optional PADPUtoJ8 Plug and Play adapters can be purchased separately for installation without cutting or soldering.
Fuel Injector Clinic specifies this connector conversion because it uses brand-new, unused injectors instead of remanufactured or core-program injectors, providing greater reliability, consistency, and long-term performance.
