Black and Decker Workmate. You clamp your engine in the grooves on the edge of the boardsby the mounts. Just make sure the spacing on the boards is set so the back is slightly wider than the front. Otherwise you will have a fly away engine
Note, my MDS 61 did want to try to make the Workmate fly so I had to add some weight to it.
Double note, the Workmate also doubles as a work table
