I used that tubular mount on my 58. What I found out is when my small block was installed it was to low in the front causing a bad angle on the front u joint. I cut the mount just below the single bolt for the motor mount, jacked it up and filled it in welding it back up. Problem solved, no vibrations at all and made for a neat package. It should be the same for the 230/250 because they use the same engine mounts. LarryW
