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.

Wow! So moisturizing!
OMGosh, this feels so good on your lips! I just got this today so I’ll have to update if the moisture doesn’t last. But so far it feels nice. I did have a slight issue with it melting onto itself in the one day it took to get to me. See photos. The tube itself was slightly concave because of the melting. But is still intact. So far though I love this stuff!

Pretty good stuff
Not a miracle cream, but I've certainly paid more for worse lip balm. The tallow is helping keep my lips hydrated, and it feels great when applied. Just got Invisalign, and I struggle with hydration normally, but this is helping keep the lips soft and smooth, and is miles ahead of the cheap drugstore brands that dry more than they help.

Worth a try, I guess.
Picked up this beef tallow lip balm for my husband. We had the worst winter and everything was so dry. He is used to using the waxy sticks you buy at the big box stores to treat his dry lips. He has been using tallow and I noticed this lip balm and thought he might like it. The stick is quite big. Thicker than the normal waxy stick you might buy at the store. In line with some of the larger sticks I have seen in the stores by some of the men's lines that are out there. He used it often and found it to work well. Did it work better than some of the waxy sticks from the store, he didn't think so but it was on par with those. He does like that it is natural. He told me that he would apply it and his lips would feel good and it would last for a while and just like any other product he would try, his lips would be dry again after a while. I would say that generally, it sounds like an average product but it's natural. Worth a try, I guess!

Very oil based. Makes me smell like a pot roast after application. Works well for under eye cream
