- Years: 1955-1991
- 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 SBC engine block compared to bolt-together types.
- One tool accomplishes accurate placement of a GM SBC 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.
