  • Engine: Cummins 3.9 4BT
  • Years: 1989-1998
  • Our patent-pending tab-and-slot version of the mock up block provides accurate mounting positions of engine accessories and bolt-ons.
  • Weighs only 26 lbs
  • 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 Cummins 4BT 3.9L engine block compared to bolt-together types.
  • One tool accomplishes accurate placement of a 4BT Cummins 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, header, front timing cover, oil filter housing, 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 timing cover.

NOTE: The 4BT was used in commercial vehicles and industrial applications, so some variations to bolt patterns may be seen.?
