HolleyHi-Ram EFI Intake Manifold Lower Half - GM LS1/LS2/LS6, Satin
LS1/LS2/LS6 Cathedral Port EFI Base Only
The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as an alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more.
The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and for 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 with max power at 7000-8000+RPM
