Here is how I have easily/securely/safely mounted stovebolt engines/blocks with that style stand.
This arrangement uses odd/unconventional relocation/realignment of the mounting fingers.
Do not worry: this arrangement is steadier, and gives a better center of gravity, that using the "normal" orientation of the fingers. The engine can be easily/safely rotated. The engine can be easily/safely rolled around (on relatively level ground).
