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.

Perfect for special occasions or to brighten up any gift!
Color: Pink
This is a lovely, easy-to-use work with the satin ribbon; it's quite pretty. I wish the roll were a bit bigger since it's very small, but overall, it's a great product.

Coolest label maker I’ve ever come across
Color: Beige
Seriously this is such a fun way to wrap presents! It comes with ink and small labels. Must buy ribbon separately. But I love this and will definitely use it for years to come! It works via Bluetooth with an app on your phone. You can customize to whatever you want!

Average quality, not as premium as expected
Color: Beige
Before buying, I thought it would be a thick, glossy satin ribbon. After receiving it, I found the material is rather thin and the texture feels quite ordinary. When used for gift wrapping, it looks a bit cheap and doesn’t match the effect shown in the pictures.
