Holley Hi-Ram LS1/LS2/LS6 105MM Intake Manifold w/ High Flow Fuel Rails - Satin
The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems. Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations. EFI fuel rails are machined for -8AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits. Cast aluminum construction. Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.
Note: the high volume -8AN fuel rail kit includes hardware and brackets to accommodate long (usually standard length) fuel injectors or short (such as Pico, or LS7) fuel injectors.
