Info

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.

  • Height (Carbureted or EFI, 2x4V Top Mount & Blank) - 11.08 to the lifter valley cover flange on engine block.
  • Base Plenum Top Mounting Flange Height - 8.42 to the lifter valley cover flange on engine block.
  • 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 - 6.50 , As-Cast Runner Cross-Sectional Area - Tapered 4.25 in² to 2.77 in²
