Our patent-pending tab-and-slot version of the mock up block provides accurate mounting positions of engine accessories and bolt-ons.

  • Precision formed returns on all weight-bearing components and tight tolerance slots create a rigid and accurate representation of the GM Mark IV, V, and VI BBC engine block compared to bolt-together types.
  • Easily positioned by hand, the days of slinging an engine on a crane in and out of your build are over.?
  • One tool accomplishes accurate placement of a Big Block Chevy engine into the chassis build of your choice.
  • 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.
  • This unique design is lightweight and comes disassembled for ease of shipping and storage.
  • Comes with hardware for exhaust, motor mounts, bellhousing, oil pan, and water pump.

These tire repair reamers work great for plug/other type repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
These tire repair reamers work great for plug/other type repairs. Gone are the days of manually fighting a hand reamer through rough rubber. This is an efficient, neat and clean way to prepare a tire for the repair. Will purchase again as needed.

Got what I paid for.
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
I dropped my drill with the bit installed. It broke quite easily. It was a relatively inexpensive so I can't complain. A higher quality harder metal would have earned 5 stars.
