Product Information

Description

The ORIGINAL Lightweight Steel LS Swap Block®

  • Engine: Gen III LS, Gen IV LS
  • Years: 1997-2020
  • Our patent-pending swap block uses our unique tab-and-slot design to provide accurate mounting positions of engine accessories and bolt-ons.
  • This distinctive 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 LS engine block compared to bolt-together types.
  • One tool accomplishes accurate placement of a GM LS 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.
