HO300-226BK - HOLLEY INTAKE MANIFOLD FITS CHEV LS1/2/6 CAT HI RAM CARB BASE BLK

Holley Hi-Ram Lower Manifold Black fits GM LS1/LS2/LS6 Cathedral Port Carburetted Base Only (Plenum-Top-Mounting Fabrication Flange Available).

The 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 carburetted 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 aluminium construction.

• Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ litre range, max power at 7000-8000+RPM.
