I have always been a little concerned about the 'engine stands' that are available for decent prices. I got one a long time ago and its similar to yours. You might have to reverse the mounting parts, do a little creative mounting, but it works. I just don't like how our 6's stick out so much further than the 8's.
The 54 235 is quite unique of all of the years. They used left over parts from the older engines but made significant improvements. I sold the one I rebuilt and completely dolled up for 3K several years ago. The purchaser keeps in contact with me and is very happy with it. Good for you Dave!
