Holley LS Hi-Ram EFI Manifold GM LS7LS1/LS2/LS6 Cathedral Port EFI fits 1 x 105MM Throttle Body - Black Ceramic Coating
Overview
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.

Beautiful!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
The sturdiness of these brackets and the quality are so good. I was worried due to other reviews I had read but these did not disappoint. They are beautiful and perfect length and weight. They are angles perfect for our shelves and a great value for as many as you get.

I made my own shelves. Stained the wood & needed brackets. Ordered a variety, different styles. These were the winner. The really added to the look, style of the shelves. Made the shelves beautiful! These reasonably priced brackets make my shelves look expensive and super high quality.

Beautiful! Exactly what I was looking for!
Size: 12 Inch, Color: Gold, Size: 12 Inch, Color: Gold
Sturdy, well contructed, and an even natural gold finish. Come with two different wall anchors and brass screws. Installation is easy. Just take your time measuring and drilling holes. I purchased finished white shelves from the closet section of home depot, $7 a piece. Gives them a nice finished look. They measure 3/4” x 11.75” x 24”. The brackets are 12” deep so there is a slight gap at the front but its not noticeable. Highly reccomend.

Find something else
Size: 4 Inch, Color: Black
I wish zero stars was an option. The quality was mediocre at best with 2 of the brackets not a proper 90 degrees and the supplied screws do NOT fit the supplied drywall anchors. They are WAY too small. What a complete waste of time and energy. I stupidly was willing to overlook the 2 defective brackets because I really only needed 3 for my shelf. That’s when I discovered that the supplied screws are too small for the supplied anchors. Now I have 6 holes in my wall that need to be patched from the 3 brackets I tried to use. Luckily I was able to back the anchors out of the wall so I could fully return this garbage to Amazon for a refund. Find something else and pass this by. Why can’t anything be easy anymore? At least Amazon has a good return policy but I really wish they would find a way to vett these products better before allowing them to list on the platform. Tomorrow off to UPS to return.
