HO300-123BK - EFI HI-RAM LS1-2-6 MANIFOLD

Suit Single GM LS 102mm Throttle Bod

Part Number: HO300-123BK

The Holley GM LS1/LS2/LS6 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 LS1/LS2/LS6 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.

Black mens coat
I didn't expect such good quality from such an inexpensive black coat, stylish, neat, looks expensive, none of my friends believed that I bought it so cheaply! No pellets appeared after a year and a half of use

Has shoulder pads.
The jacket has shoulder pads that don't necessarily show on the image in the purchase area. Pretty pronounced so if that's not your thing definitely stay away. Got lucky and it doesn't look too bad on me but it took so long to receive the package I don't feel like going through the refund process so I'm dealing with it. Quality is great tho
