I just did this with a 250 inline 6 to a 350 v8. There are 2 perches that are mounted to the frame. These are the same for 230,250 inline 6's and v8.On 292 inline 6's one side is differen't. Just go to a jobber and get motor mounts for a 65 chevy or gmc. Bolt them directly to the block. theres a hole in the center of the mount that bolts to the perches.
