  • Our patent-pending tab-and-slot version of the mock up block provides accurate mounting positions of engine accessories and bolt-ons.
  • This unique design is lightweight and comes disassembled for ease of shipping and storage.
  • Precision formed returns on all weight-bearing components and tight tolerance slots create a rigid and accurate representation of the Gen III Hemi engine block compared to bolt-together types.
  • One tool accomplishes accurate placement of a Hemi engine into the chassis build of your choice.
  • Easily positioned by hand, the days of slinging an engine on a crane in and out of your build are over.
  • It's designed to bolt to your transmission while also permitting the attachment of oil pan, motor mounts, headers, water pump and intake.
  • Save time and money and work more safely.
  • Durable steel construction resists heat from welding, so unlike foam blocks, custom motor mounts can be fabricated right on the block.
  • Comes with hardware for exhaust, motor mounts, bellhousing, oil pan, and water pump

Perfect Everyday Cap – Cute, Comfortable, and Sporty
Size: One Size, Color: Wonder Alumina Grey/Off White/3
I really love this adidas Women’s Sport Essentials Baseball Cap! It’s lightweight, comfortable, and fits perfectly without feeling too tight. The adjustable strap makes it easy to get the right fit, and it stays secure even when I’m active or on the go. The design is simple but stylish, and it goes with almost any outfit—great for casual wear, workouts, or sunny days. It also does a good job keeping the sun out of my face without feeling heavy or hot. Overall, super cute, practical, and great quality. Definitely a staple cap I reach for all the time!

Adidas Classic Adjustable Cap – 2-Pack (Black & White)
Size: One Size, Color: Black/White/2, Size: One Size, Color: Black/White/2
I recently purchased this Adidas cap set, and I’m extremely happy with both the quality and the comfort. The material feels durable yet lightweight, making it perfect for everyday use or outdoor activities. The adjustable strap ensures a perfect fit, and the classic Adidas logo gives it a clean, sporty look. Both colors look great — the black one is sleek and versatile, while the white one is fresh and stylish. They keep their shape well, even after multiple uses. Overall, this is a great purchase for anyone looking for a comfortable and well-made cap. Highly recommended!
