Introducing the Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold, a cost-effective alternative to fabricated sheet-metal designed for high-performance applications where induction system height is not constrained. When coupled with the high-flowing LS1/LS2/LS6 style cylinder heads, this Hi-Ram intake showcases exceptional potential for both naturally aspirated (N/A) and forced induction applications, all while maintaining an economical price point. Its aggressive, bold, race-bred styling makes it the perfect choice for various applications, including drag racing, muscle cars, marine, off-road, sandrails, pulling trucks, track, street-rod applications, and more!

Key Features:

  • Modular base design allows flexibility for a wide range of carbureted and EFI tops, appealing to builders and fabricators as the foundation for custom induction systems.
  • Optimized runner length and tapered cross-section designed for superior performance across a diverse range of engine configurations.
  • EFI fuel rails machined for -8AN O-ring Fittings, featuring passages large enough to handle high fuel flows and dampen pressure pulsations in the fuel system; standard with EFI Hi-Ram kits.
  • Constructed from durable cast aluminum.

Specifications:

  • Intended for use on naturally aspirated or forced induction engines in the 6.0 to 7.0+ liter range, achieving maximum power at 7000-8000+ RPM.
