1681CI 1963-1977 Small Block Ford cast iron 5-9/16" water pumpSmall block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller, an increased vane count and a reduced casting to impeller vane clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. FlowKooler introduced the first hi flow pumps and continues to improve

Small block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller, an increased vane count and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Ford engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Wonderful, Gripping, Suspenseful, and Miraculous!
Format: Hardcover
The first thing I thought when I started reading Ann Patchett’s new novel, “Whistler” was: “Oh no, this is SO GOOD it’s going to go by too quickly!” I was right, and the only remedy to that is to read it again – it’s that great. Patchett has created a matryoshka doll of a novel with a story inside of a story inside of story, and they are ALL wonderful, gripping, suspenseful, and miraculous! The inciting incident that sets off the story takes place in the Metropolitan Museum of Art in NYC. As Daphne and her husband Jonathan take in the art, Jonathan notices that they are being followed by an older man who turns out the be Daphne’s former stepfather, Eddie, whom she hasn’t seen in 44 years (since she was nine) but who was pivotal in how her life unfolded. Through the narrative, Daphne, and her sister Leda, relive long forgotten memories from their brief but impactful time with Eddie, now understanding what they couldn’t as children. Patchett has written about blended families, divorce, and stepparenting before, in her wonderful 2016 novel “Commonwealth”, and in some of the personal essays about her own childhood. So, she knows what she’s talking about! Patchett beautifully evokes childhood nostalgia and skillfully portrays the way the past can sometimes seem more immediate than the present, highlighting reconnection, reconciliation, and grace. Thank you yet again, Ann; this was just the book I needed right now!

One of Ann Patchett’s best novels.
Format: Hardcover
“Whistler,” by Ann Patchett, Harper, 320 pages, June 2, 2026. Daphne and Jonathan Fuller are visiting the Metropolitan Museum of Art when Jonathan notices an older man following them. They go up to the next floor and the man is still following them. It turns out he is Eddie Triplett, Daphne’s former stepfather, who was married to her mother for a little more than year when Daphne was nine. They haven’t seen each other in almost 45 years, but he recognizes her. It is a chance meeting. Daphne teaches literature at a private school and Jonathan is a retired hospital administrator. Eddie is an editor at Random House, but he wasn’t at the office this day because of a water main break. Daphne visits her sister, Leda, to tell her about the encounter. Flashback to 1980, when Leda was having an appendectomy, Eddie was driving Daphne to the hospital in a snowstorm and they were in an accident. Daphne had to climb out of a car window and walk for help. After that, her mother divorced Eddie. Of course, there’s more to what happened. This is a wonderful story about adults looking back at the choices they’ve made and the choices that others made for them. It is about the small things that impact our lives and memories of childhood. It is about families, love and bravery. This is one of Ann Patchett’s best novels.

Another amazing book from a talented author
Format: Kindle
This is one of my favorite authors so I knew I would enjoy this book and once again, the characters seemed so real like people I knew personally. I very much enjoyed Daphne and Eddie’s relationship and I loved learning about Eddie and Daphne’s mother’s life together and why things played out the way they did. This book truly shows how people can impact us forever regardless of how long they were in our life. There was so much beauty in this book despite the loss and sadness at times. I received an advance review copy for free, and I am leaving this review voluntarily.

A book that hugs back.
Format: Hardcover, Format: Hardcover
I picked this book for my brother-in-law when we were celebrating my sister’s pregnancy, and the title ‘Why a daughter needs a dad’ sealed the deal. The illustrations are beautiful and full of tenderness. The messages on each page are simple and meaningful. I could so clearly picture him reading it to his baby girl someday. It’s the kind of book that isn’t just read – it’s felt. A thoughtful gift for someone you love – especially during such a special season of life.
