Fuel Rails; Cast Aluminum; For Use w\/LS1\/LS2\/LS6 Cathedral Port Heads;\u003c\/p\u003e\u003cp\u003eThe Holley GM LS1\/LS2\/LS6 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 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 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 configurationsEFI 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePort Size 2.49in. Height X 1.21in.
