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.

This product really Works !! Wow , I have had Ezema for 30 years and this helps !!!
I really was tired after 30 years of using expensive ointments and creams .. So hesitant about a pill formula, I said, Why not ? And I do love this Company! I had used the Mother of All Creams before and loved it but the price got a little too expensive? But I still love it ! So I tried this pill for my Ezema and let me tell you something, I was amazed at how fast it cured up my red itchy rash that had annoyed me for all last Summer ! I had even been bitten by a tick and it did not even itch !! Not joking People ! But it says take 2 pills a day , I take 3 daily because my Ezema is Chronic ! Thanks so much Puriya !! And please keep producing this product !!! M.W.

Not a recommend , was refunded
Again, maybe it helps others. Does nothing for me. I went all out and purchased the face wash, Mother of all Creams and these supplements. My skin actually got more itchy and felt greasy. So over $70. down the drain for me. The company refunded me for all 3 items. They stand behind their product. Perhaps I have a sensitivity or something of an allergy to an ingredient or 2 in the formulas. I followed instructions and it was after about a week and a half of use I just had to stop. I have always had sensitive skin.

So Far So Good
I have only been using it for about half a month, I take a lot of supplements daily, for I believe in them at 83 years old they work for me. No real health issues, other than this skin thing, the itching and burning, creams help, but you need to almost take a bath in them almost daily. I love the inside out concept of control or stopping the itching and burning. I can say that the itching and burning seems less after half a month of use, but only time will tell, that is the real test. TIME
