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 ?

Good basic backpack
Color: Black, Size: 16 Inch
Good size backpack. Unfortunately the front side zip pocket does not fit 13 in laptop. Otherwise it's a pretty generic backpack. Material looks and feel good

Such a Pretty Backpack.
Color: Apricot, Size: 16 Inch
I love this backpack. It's very beautiful and very comfortable to wear. I mainly bought it for a trip to Prague, but I love this bag so much I started using it daily. The quality feels good all around. The zippers are really smooth and the straps are very comfortable. One of my friends happened to take such a liking to it that she ordered her own too. The different pockets allow for easy organization and quick access. It's very stylish and so far, its been quite durable. I've used it for a little less than 5 months and a trip to the other side of the world, but its still holding up.
