Holley EFI LS3/L92 Hi–Ram Intake 102mm - (Rectangular Port)
The Holley GM LS3-L92 Modular Hi–Ram intake manifold is introduced as a cost effective 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 LS3-L92 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 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.
