I haven't done that myself but do know it has been done. So without answering your question I just want to encourage you. Go for it.

You are going to need oldsmobile frame side engine mounts from a similar body car.

I believe you have to use either two small block or two big block style mounts. Make sure you don't use one of each.

If I am correct, you can use the same mounts. But they will have to be moved. Do they look like in this pic?
Let us know.
