Overview:

The new Holley Single-Plane Race intake manifold were designed with performance in mind. They feature a race bred, two piece split feature that was previously only found on the most expensive race intakes. The manifold will fit GM LS Gen III engines with LS3/L92 heads and are intended for 4150 style square bore flanged carburetors or throttle body EFI. The LS Race single-plane intake manifold was designed for hi-performance/racing engine applications, 5.3 to 6.2+ liter displacement, and maximum engine speeds of 6000-7000 rpm, depending on the engine combination. This single-plane design provides optimal performance across the RPM spectrum while providing maximum performance up to 7000 rpm. The Holley LS Race manifold incorporates a split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, making custom porting and matching a snap. With shoulder bolt locators and O-ring seal, reassembly is simple and precise. Technical Data: ? A-B Height - 7.25" (0° carb flange angle) ? Port Size- 2.59" Height x 1.28" Wide ? Carburetor Flange - Standard 4150 for up to 1-3/4" diameter throttle bores ? As-Cast Runner Cross-Sectional Area - 4.5 in² at the runner entry tapered to 3.2 in² at the flange exit

Informative and fun book
Format: Hardcover
The story itself is very informative and playful in its approach to helping the reader understand the process of selecting and training service dogs. The star that was knocked off is not reflective of the product, but the shipping process or the packaging department which delivered another book with a ripped dust jacket. In reality the intended recipient will take that off anyway, so I am not returning it. It seems wasteful. However, if this gift was intended for anyone other than a family member, I would have. Amazon needs to train its packaging departments are better. But I suppose as long as we all keep buying, they will not.

Inspiring story and gorgeous illustrations
Format: Hardcover
Such an inspiring story about life, love, courage and all of the people that work so hard to train and care for service dogs. The deep bond between a service dog and their owner is such a beautiful thing to see. I love seeing people living their best life with their service dogs out in public and when I read this book I felt it was the perfect way to spread awareness and hope especially to young kids. I highly recommend this book and I hope Canine Companions comes out with more in the future either following Andy’s life or maybe from a childs perspective who’s parents adopt a canine companions dog and how her/his life improves as a result.
