This kit is designed to mount to the original crossmember frame mounting holes on SBC V8 trucks and allow the use of side mount car style engine mounts. You can also use these to convert your 6-cylinder truck to a SBC V8 (will require drilling). This kit will also enable you to run solid motor mounts in high performance applications. 2WD applications only. These engine mounts are made from steel and feature a black powder coated finish.
