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 compact and reliable 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, Alternator, P/S pump with reservoir, and the crank damper. All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, 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. The Premium Mid-Mount system comes with dress up pulley covers and an SFI certified damper. Partnered with this damper is a billet 6061-T6 aluminum hard anodized crank pulley. This system is ready for the racetrack if you want to play or just be ready for anything on the street.

Fun probiotic
My favorite part about this one is that it’s a one pill dose. I take more pills than ideal so anything that only requires one pill is a selling point for me. As a probiotic, I’m giving it 5 stars for meeting expectations based on the listing even though it’s probably a 4 star product for me personally. This comes in a surprisingly compact capsule. I’m not an expert of all the options available on the market currently but it’s one of the smallest shelf stable probiotics I’ve taken on top of only requiring one pill a day. There is a mild scent and taste that I assume is due to the pineapple powder. It’s not distinctly pineapple but it has a hint of the sharpness. That said, I didn’t find either the flavor or scent strong enough to be off putting. Effectiveness is a little more nebulous. I didn’t have any negative effects and my gi tract seems to be running smoothly. 25 billion cfus is lower than what I find to be an optimal dose for my system but I wanted to try it out to see if 50 billion was overkill. I think the higher dose is a better fit for me because while things were fine on this, I feel like it did see even more improvement at my prior level. That said, this could be a great option for someone who wants a little more than a low, baseline dose but may be too sensitive for the 50 billion and higher options. Value is decent. It’s not the absolute cheapest but hangs out in the bottom half of the price per dose spread I’m familiar with.

New Testament study at it’s finest
Format: Hardcover
Wow, what a book. If I could only take one book as a resource to the Bible it would be this book. Comprehensive, detailed, scholarly scaled down to average comprehension, and relevant. Did I agree with everything Dr. Wright stated? No, but this is a rock solid book that should anchor your library. It is a an enormous book— it literally weighs 4and a half pounds. At 987 pages (889 actual text pages), it is not for the faint or weak at heart. The book literally covers everything you need to know about the New Testament in the Roman world, from history and religious backgrounds to book by book studies and concluding with textual criticism, the development of the canon and the responsibilities of the Church in living the life expounded on in the scriptures. Very highly recommended.

Great Bible study book
Format: Hardcover
Highly recommended. Anyone who wants to get deeper into God’s Word can learn from this book. While it is not light reading, it is very readable. Cultural context is very important (the Bible was written FOR us but was written TO ancient peoples living in a different culture) and especially so in the Old Testament. This book is rich in explaining cultural context. I learned so much from reading it.
