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.

NICE for soups!
Style: 34 Ounces, Size: 34 Count
We try to keep these in the house. They are REALLY nicely sized and work great for soups. They are AWESOME for soups and the only disposable plates I feel comfy using for large stews and such. Makes cleaning easy because I don't HAVE TO CLEAN! They are a bit more expensive than otherd disposable plates, but they are worth it. Pretty heavy duty plates that are thick and great for heavier foods. <3

Favorite compostable plates ever!
Style: 34 Ounces, Size: 34 Count, Style: 34 Ounces, Size: 34 Count
I’ve been using the Dixie Ultra Extra Large Compostable Paper Bowls, and I can honestly say I absolutely love them! They’re sturdy, deep, and hold generous portions, perfect for everything from hearty soups and pasta to big salads or even snacks for movie night. Unlike other paper bowls, they don’t get soggy or collapse, even with hot or liquid-heavy foods. Another huge plus for me is that they’re compostable, so I can enjoy the convenience of disposables without the guilt. They’re strong, reliable, and environmentally friendly, which is a rare combo! If you’re looking for durable, eco-conscious paper bowls that can handle anything you throw in them, these are a must-have. Highly recommend!

No more washing pozole/menudo bowls for me
Style: 34 Ounces, Size: 34 Count
Very sturdy for a paper plate. Used these for pozole at a party and saved me the hassle of washing plates. Good size, bigger than you think. When serving it does get hot so use something underneath so you don’t get burned.
