Holley LS Hi-Ram EFI Manifold- LS7 EFI with 105MM Throttle Body

The Holley GM LS7 Modular HiRam Intake Manifold is introduced as a cost effective alternative to fabricated sheetmetal for high-performance applications where induction system height is not limited. Coupling this HiRam intake with the high flowing LS7 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget minded cost. Aggressive, bold, racebred styling will make bad intentions clear for drag race, muscle car, marine, offroad, 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 HiRam kits.

Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 70008000+RPM.

These parts should be used for the following applications: Racing/Performance/Street Rodder where hood restrictions are NOT a consideration. Top can be mounted forward or backward.

Holley EFI LS main harnesses have a map sensor connecter designed for use with an LS1/2 style map sensor. The 558-416 is an adapter harness that can be used to adapt any LS harness that uses a LS1/2 MAP sensor connection to a LS3 MAP, which is recommended for this manifold.
