    Holley 300-226BK Details

    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 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.

    • Features:

  • Port Size – 2.49” Height x 1.21” Wide
  • Mounting Flange Gasket Type – Standard LS3 Molded O-Ring
  • Plenum Top Gasket Type – 3/32” Round O-ring Cord
  • Runner Length – 6.58”, As-Cast Runner Cross-Sectional Area – Tapered 4.25 in² to 2.53 in²
