HO300-226 - HI RAM BASE ONLY LS1 LS2 LS6

Manifold Base Only Suit Carburettor Application

Part Number: HO300-226

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 aluminium 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.
Features:
Port Size - 2.49" Height x 1.21" Wide
Mounting Flange Gasket Type - Standard LS3 Molded O-Ring
Plenum Top Gasket Type - 3/32" Round O-ring Cord

slightly annoying to hang
Color: Brown
A little annoying to hang but look great and seem to be holding up well! I have heavy plants on them and no issues at all!

Functional, Look Great
Color: Brown
These were nice corner shelves that were easy to install, and look great. There are plenty of other options on Amazon that offer more shelves and/or at a lower price, but these ones look nicer than most. Overall they're pretty easy to install. It's not exactly a two-person job, but it is easier if you have help - someone to hold the shelf and a level, and the other to mark the holes. My only other recommendation is to check your L-brackets before you do anything. Some come bent inward, some bent outward. If they're really crooked it will make it hard to wedge the shelf into the corner and may result in uneven measurements/holes, so make sure you straighten them out first.

great shelves
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 36inches
These are a a great set of floating shelves! They were easy to install, feel sturdy, and look clean and modern on the wall. The set of three is perfect for displaying decor, photos, plants or small storage items while adding extra space without taking up room. Great quality, stylish, and a simple way to upgrade any space. They work perfect for my figurines to be displayed.
