HI RAM BASE ONLY LS1 LS2 LS6 CATHEDRAL PORT, CARB ONLY

Description

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifoldis 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 LS1/LS2/LS6 style cylinder heads has outstandingpotential 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 widerange of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.
Runner lengthand the tapered cross–section designed toperform 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 pulsationsin the fuel system and come standard with EFI Hi-Ram kits.
