Overview:

Holley's Mid-Mount Accessory Drive System is now offered for the serious racer in mind. If you need a front drive system for your LS engine racecar, they are now available without air conditioning and power steering depending upon your needs! Holley's Premium 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 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, alternator, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation. This system is ready for the racetrack if you want to play or just be ready for anything on the street.

Features:

  • Bracketless accessory mounting with ultra-easy assembly
  • Bottom outlet heater hose options for swap application clearance
  • LT1 style premium 150 amp alternator
  • LT1 style water pump cartridge design
  • Steam tube input port
  • Shortened top outlet nipple for more radiator hose turns and routing room

A beautifully written and illustrated tale of kindness, courage and (imaginary) friendship
Format: Hardcover
A beautifully written and illustrated tale of kindness, courage and friendship (even if the friend is in your imagination). This is a great picture book for building self-esteem and for helping early learners to discover ways to overcome obstacles by showing how upbeat confidence boosting self-talk is the way to go. I adore this beautiful family and how the climb up the slide's stairs is so relatable-you just feel the endless up, up, up as you ascend, like climbing up the stairs of the high dive and looking down and just that whoosh of fear that vertakes you from the seemingly dizzying height. I love the kindness on all the adults' faces and the cute expressions from the child. The lion is magnificent. I love that it gives shape to a child’s imaginary friend and that this friend is a true safety net -which is really the child being their own safety net. The end pages are bright orange and sunny, using the cute lion face in the pattern and all the illustrations, which are predominantly blue and yellow/orange illustrations are the perfect backdrop for the tumble of dark curls on the child’s head which allow the size of the lion to appear gigantic, and yet, calm and sweet like a kitty cat. Very sweet book! I love its message of bravery, confidence building and how you can truly be your own best friend.

Sweet Story about facing your fears!
Format: Hardcover
A trusted comrade, a little girl’s lion is always there. Her lion helps her through times of stress, or if she makes a mistake, or if she is nervous. A girl and her lion, the dream team! One day the little girl goes on a new adventure, a brand new slide arrived at the playground and she can’t wait to try it with Lion. The ladder is a bit taller than she thought and with every climb, uncertainty starts to creep in. This slide is so high! How will we ever get down? The young girl wonders. Turning back towards Lion (since this is usually the part her brave lion steps in to help) she notices that he is afraid too! This is such a sweet story about facing your fears! I love the bright yellow and orange with blue color palette. Having a lion inside to symbolize bravery is such a wonderful way to help young readers with facing their fears. We love to teach our children that fear is a healthy response, it’s a message that our body is giving us! It is also healthy to work past that fear (although sometimes we need some help doing just that).

Love!
Format: Hardcover
A little girl feels like she can courageously tackle anything with the help of her brave lion. When she climbs a tall slide, however, and her lion becomes afraid, she must summon her own strength to overcome her fear.  I especially love the illustrations in this validating and reassuring read.
