Overview:

The Holley GM LS7 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 LS7 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.

Solid purchase for everyday use.
Color: Orange
Can’t really say to much about these. They have a strong magnet and are durable enough for everyday use. I use them to hang my compression leggings from normatec as well as other accessories. They work well and are at an affordable price. Hook size is ok. I feel like most items you would hang have no issue. Have not loaded them with to much weight but I’m sure they can hold a fair amount.

can always use more
Color: Black
I keep buying more of these for fitness equipment storage. I got long and short hook models and very strong magnets hold up pull down attachments weighing 10lbs or more. Works great for belts, carabiners and anything you want to organize in the weight room.

Definitely holds 5lbs, but not 8 lbs.
Color: Orange_J_Hooks
It holds my 3lb weight, also my 5lb weight. But it doesn't hold them both - 8 lbs- as it slides off my metal door.
