Hooker's new cast iron small-block Chevy exhaust manifolds offer an increase in performance and visual appearance over stock-style manifolds. Their compact design fit into a wide variety of replacement and engine swap applications. This means you get the traditional look and easy fitment of a stock style exhaust manifold but now with a smoother, cleaner appearance, plus more modern features. These manifolds are cast out of high silicon-molybdenum ductile iron for high temperature strength and better resistance to oxidation and cracking. Internally these manifolds have a larger than stock 1 5/8-inch cross-sectional area and 2 1/2-inch outlets for better air flow and improved performance. Designed for rectangular port heads, these manifolds fit many popular GM applications including standard straight and Vortec straight plug head designs. Finishes include natural, silver, black, and titanium ceramic. Gaskets and hardware are included, along with weld-on flanges to aid in downpipe installation.

The Last Book You Will Ever Need About Starting Your Own AI Business
Format: Paperback
I first purchased this book on Audible to listen to during a long road trip, thinking it would be an interesting way to pass the time. What I didn’t expect was just how engaging and eye-opening it would be. By the time I finished listening, I was so excited about what I had just learned that I immediately called my wife and asked her to order me a hard copy. I knew this was a book I needed to have on my shelf, not just to reference but to truly study.
At the time, I had been toying with the idea of starting an AI design company and creating print-on-demand products. However, this book introduced me to the concept of AI androids and their incredible potential, completely shifting my perspective. The insights and possibilities it presented made me rethink my approach and explore entirely new directions.
Beyond just being informative, the book is exceptionally well-written, with clear, concise instructions that make even complex concepts easy to grasp. Whether you're a complete beginner or someone with experience in AI, the guidance provided is structured in a way that makes it accessible to anyone willing to learn.
Although I haven’t officially started my journey yet, this book has given me the confidence and motivation to take that first step soon. I’m grateful to Dan for sharing his knowledge in such a practical and inspiring way. If you're even remotely interested in AI, technology, or the future of innovation, I highly recommend giving this book a read—you won’t regret it!

Review of The Instant AI Agency
Format: Paperback
The Instant AI Agency is more than just a guidebook—it's a wake-up call to dream bigger, move faster, and claim your stake in the AI-driven future. From the very first chapter, you're pulled into a world of possibility where everyday people—regardless of technical background—can build thriving businesses by tapping into the AI gold rush.
What makes this book stand out is its crystal-clear messaging: you don’t need to be a coder or a Silicon Valley insider to win big. The author has a gift for breaking down complex ideas into bite-sized, actionable steps. It feels like you're getting advice from a mentor who actually gets it—the overwhelm, the fear of starting, the endless rabbit holes. And yet, page by page, they remove every excuse and replace it with fire-in-your-gut motivation.
What really inspired me was the relentless encouragement to just start. This book doesn’t dwell in theory. It gives you blueprints, proven playbooks, and real-world case studies of people who went from zero to six figures—fast. And it’s all wrapped in a tone that feels like a friend hyping you up, saying: You got this.
If you're someone who’s ever felt stuck in your 9–5, if you’ve dreamed of building something online but didn’t know where to begin, this book is your sign. It’s practical, empowering, and exactly what this digital moment needs.
I closed the final chapter feeling fired up, focused, and fearless. The Instant AI Agency doesn’t just teach you how to build a business—it shows you how to take back control of your time, your income, and your future.
5/5. Game-changing. Life-shifting. A must-read for every digital dreamer.
