Overview:
Holley's Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design (Patent Pending), where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. Among the many swap friendly features are bottom heater outlets for clearance in tight applications. The Holley designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with that of the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated.
The Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines.
When we say "complete", we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, A/C compressor, Alternator, P/S pump with reservoir, and the crank damper. All pulleys and the belt are supplied.

Out of Control with Technology
Format: Hardcover
I found the book very interesting! The authors did a great job of discussing the benefits of different social media sites. While the sites were intended for good use, there is always a downside. Each of the sites were exploited over time for a use other than intended. While this is by no means a surprise, it is amazing how others were quick to use the sites for illegal purposes. The history of how some of the sites were developed was interesting too. Of additional interest was the amount of notes included in the book. A third of the book is devoted to this alone. It shows the level of thoroughness the authors took to allow readers to delve deeper into topics discussed in each chapter. The most pressing question for social media: What is the next level of advancement?

All's fair in Like and War
Format: Hardcover
Is Mark Zuckerberg responsible for exacerbating the killing fields on the South Side of Chicago? What is China's Golden Shield Project and what might it mean for you? Did Michael Flynn have any good ideas before his fall from grace serving in the Trump administration? Read this book and you'll get the answers to these questions and many more.
This book takes a notion with which most readers are likely already familiar - the internet has graduated from its nascent status as a series of tubes connecting nerds and defense contractors to that of an ineffably complex globe-gobbling organism engaged every hour of every day in the instantaneous distribution of information spanning all spectra of human activity - and combines it with one not so well established in the popular imagination - we (or, at least, everyone who uses the internet) are all potential foot soldiers, willing or not, in the online and offline wars still raging as well as those yet to come.
Written in succinct, snappy prose, the book tells the story of the internet from its peculiar vantage point at the intersection of social media and military conflict with its arguments firmly based in factual and expert analysis. Those seeking to validate a particular political slant or ideology should look elsewhere.

Insightful but troubled
Format: Hardcover
This book could have been so much more but it fell short. The book does capture a new phenomenon sweeping the world. The growth of social media is that phenomenon. The book does a good job chronicling the growth of social media and its impact on a general scale. Through that growth opportunities were created. The book does a good job of listing how people, groups and countries exploit these opportunities. They advance their respective agenda various ways on social media. I loved the pages which talked about how AI can create fake news with all of the authenticity of an eye witness account. The book lists impacts of these trends with crystal clear words. You can see impact clearer than any other source out there.
The negative is the bias of the authors. Who the authors voted for in the last election screams out with every chapter. They use the topic as a club to bash republicans, President Trump, and conservatives. They miss how Democrats were playing the same games as Trump before Trump. This bias causes a reader to lose the message and dangers through politics. David Plouffe, the Obama campaign manager in his book "The Audacity to Win" said he used social media in 08 election. Funny how these people ignore those events to focus on what Republicans do. I also think their constant drum beat of what the Russians do creates a false election that they stole the election. The authors forget the failed policies of Hillary.

Documents the influence of American Eugenics on the Holocaust
Format: Hardcover
American Court decisions, and what some call the genocide of Native Americans, was one major source of inspiration behind Nazi policy against both the Jews and people that the eugenic scientists considered inferior races. American policy also was very influential in inspiring the Nazi goal of lebensraum, expanding the Germanic population and reducing, and making slaves, of the Slavic peoples (Poles, Russians and other Eastern populations). Following Hitler's rise to power, Lebensraum became an ideological goal of Nazism and provided for them justification for the German territorial expansion into East-Central Europe. After all, the Americans decimated the naïve population of America so, the Nazis reasoned, how is that different from the decimation the native population of Eastern Europe? Some even referred to Ukrainians and other Slavic people as "Indians."
Reservations for Native Americans was a factor justifying the concentration camps for Jews, only a few of which were death camps, and this is one reason why the Nazis got away with the Holocaust for so long. It was not until after the war when the Soviets liberated the death camps that we knew for certain the extent of the genocide goal of the Nazis. The main extermination camps were Belzec, Sobibór and Treblinka, which served as "death factories." Auschwitz II–Birkenau was a combination concentration/extermination camp.
Anti-Semites, eugenicists and racists inspired by Darwinism in the U.S. helped inspire those in Germany, and vice versa. The US was “a global leader in ‘scientific’ eugenics,” so naturally the German scientists would have to rely on American research and law (page 8). The author covered only briefly the well-documented important influence of Darwin and mentioned evolution only in connection with the evolution of racism (p, 114). Conversely, the eugenics idea and movement was discussed 28 times, such as page 8 where the author documents that eugenics was the basis of both the Nazi Germany and American discrimination laws and policy.
The support of the U.S. to Nazi German went well beyond that. U.S. bankers and industry, even the weapons industry, invested heavily in the Nazis war machine. Nazis borrowed ideas from U.S. books, such as the 1916 American best seller racist book titled The Passing of the Great Race and other propaganda, such as that developed in World War I. The U.S. refused to admit significant numbers of Jewish refugees, such as in 1939 the United States refused to admit over 900 Jewish refugees who had sailed from Hamburg, Germany, on the St. Louis to the West. Denied permission to land in the United States, the ship was forced to return to Europe where many died in Nazi German camps. The most famous example is the State Department rejected Anne Frank's attempt to enter the United States (pages 53,116, 149).
