Fuel Injector Clinic 1440cc High-Z Fuel Injector Set (ish03-1440h) - Holley GM Composite Intake
Give your high-horsepower Holley GM combination the fuel capacity it needs without giving up the control and drivability you want on the street. The Fuel Injector Clinic 1440cc High-Z Fuel Injector Set, part number ish03-1440h, includes eight saturated, high-impedance injectors rated at 1440cc/min, or 140 lbs/hr, at 43.5 PSI and 160 lbs/hr, or 1700cc/min, at the OE 58 PSI fuel pressure. Positioned between FIC's 1200cc and 1650cc offerings, the 1440cc injector delivers a strong balance of increased fuel capacity, excellent idle performance, and precise short pulse width control for powerful gasoline, E85, and race-fuel combinations.
The ish03-1440h is built with a stainless alloy valve construction that provides exceptionally broad fuel compatibility, including pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels. Each set is precisely matched using Fuel Injector Clinic's proprietary Data Match Technology. Every injector is individually serial numbered, with its results documented on the supplied Data Match Sheet to provide detailed flow-matching and latency information for accurate calibration. FIC flow tests and rates these injectors at 43.5 PSI using CF-16B calibration fluid maintained at 90 degrees F, while plug-and-play GM ECU data is available from Fuel Injector Clinic to further support the tuning process.

Fitment
Designed for Holley GM composite intake applications. Fitment is based on the intake, fuel rail, wiring, and overall fuel system configuration rather than a specific vehicle year, make, or model. If your combination uses aftermarket fuel rails, a modified intake, or another unusual fuel system configuration, contact Beefcake Racing before ordering to verify proper injector fitment and connector requirements.
FAQs
What fuels are compatible with Fuel Injector Clinic ish03-1440h injectors?
The stainless alloy valve construction gives the ish03-1440h broad fuel compatibility. Fuel Injector Clinic specifies compatibility with pump gasoline, E85, Q16, VP Import, FTW, and other MTBE oxygenated race fuels, making the 1440cc injector a versatile option for both street-driven and race-oriented performance combinations.
Why choose the 1440cc injector instead of the 1200cc or 1650cc FIC injector?
The 1440cc injector fills the capacity gap between FIC's 1200cc and 1650cc offerings. It provides additional fuel delivery for higher-horsepower combinations while retaining excellent idle performance, superior short pulse width control, and the drivability needed in street-driven vehicles. The correct injector size ultimately depends on horsepower, fuel type, fuel pressure, and the requirements of your specific combination.
Why Buy Fuel Injector Clinic Injectors From Beefcake Racing?
Choosing the right injector means matching fuel capacity with your horsepower goals, fuel type, operating pressure, intake, fuel rails, electrical connections, and tuning requirements. Beefcake Racing can help you determine whether the Fuel Injector Clinic ish03-1440h is the right match for your Holley GM composite intake and performance combination.
