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.
