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!

Features:

  • Port Size – 2.49” Height x 1.21” Wide
  • Mounting Flange Gasket Type – Round 3/32” O-Ring Viton, 3” I.D.
  • Plenum Top Gasket Type – 3/32” Round O-ring Cord
  • Runner Length – 6.50”, As-Cast Runner Cross-Sectional Area – Tapered 4.25” to 2.77 in²
