G Force Performance GF-EJ-BBC-DIY Features:

G Force 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.
