HO300-122BK - EFI HI-RAM LS1-2-6, w/92MM T/B

Suit Single GM LS 92mm Throttle Bod

Part Number: HO300-122BK

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 aluminium 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.

The Book I Meant to Write
Format: Kindle
While doing my master’s degree in international relations, I completed a master’s thesis on Xi Jinping Thought (which, like the authors, I shortened to Xi Thought). I considered writing a book on the subject since there wasn’t a lot in English, but I no longer feel the need. This book fills every gap that was present. Well written and informative, it is the quintessential English source in Xi Thought. The authors put Xi’s political thought in a consultative Leninist paradigm and define that context clearly. Each chapter elucidates a little more and puts Xi thought front and center in China’s current transformation. I consider it a must read.

Great read and most importantly very topical
Format: Audiobook
The writers use published work of Xi and Chinese government official statements to describe the true nature of this most important Chinese leader who will have profound impact on the total world.Like it or not it is essential for all of us to really what he is preparing his nation for the vision he has.Americans are naive and totally ignorant.

Pure anti-China propaganda
Format: Audiobook
From the first few sentences they get the name of the ruling party of China wrong and it only gets worse from there. This is purely a work of western propaganda and in no way academic or objective. I've studied China for many years. You will find nothing of value from this book. All of their achievements are minimized or disregarded entirely. You will also notice that very little data is presented if any at all.

Great analysis on a super important topic
Format: Hardcover
Excellent analysis of what is potentially the most important flash point on earth - while we are all looking the other way to Iran. The vast majority of Americans have no idea what would happen if (and I hope not when) China tries to take Taiwan. It would change technology and geopolitics instantly, and not in our favor. We are not prepared. A lot is at stake. Even a cursory reading of this book would better inform any reader. (And how could that one star reviewer think this is a novel? It doesn't remotely sound like a novel, even in the description. Insert eye roll emoji here.)

Will 500 5 stars defeat a mistaken rating?
Format: Hardcover
The future of the planet depends on this book and it received one star as a "mistaken novel!!" DO NOT look only at the stars, this seminal, recent, scholarly text, at an amazing price for the content (cf Springer for $300 US), outlines the disasterous imminent global economic and even nuclear consequenses brewing NOW in the Strait. I'm completing my third doctorate on simulating Strait diplomacy and military models, and Adam Liff's recent Cambridge article (open access) is a great preview of this amazing and crucial text-- Bayesian math plus Baha'i consultation are urgently needed to mitigate THE global trigger and planetary flashpoint which is about to destroy the global economy, or... worse.
