Introducing the Holley GM LS7 Modular Hi-Ram Intake Manifold, a cost-effective alternative to fabricated sheet-metal designed for high-performance applications where induction system height is not restricted. Combining this Hi-Ram intake with the high-flowing LS7 style cylinder heads presents exceptional potential for both naturally aspirated (N/A) and forced induction applications at a budget-friendly cost. Its aggressive, bold, race-bred styling makes a powerful statement 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 for flexibility, accepting 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 wide 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.
