Texas - Just my $.02 worth. First - no, you won't need an adapter for that stand. However - the long block length and very top heavy 235 really demands a much wider and longer stance 4 leg (U or H leg design) to best support your engine when mounted and being worked on.
The top heavy engine tends to roll/rotate (flops over) with little to no effort or warning because the rear mount legs are not centered for the blocks weight distribution. I know of several Bolters that have mentioned in the past having their engines damaged and or almost being severely injured when the engine flopped over on the type of stand you showed, with the stand ending up going over as well.
At the least, that stand needs to have the front half of the H lengthened to widen the stance to prevent the stand toppling over when the engine throws it weight over during rotation.
There are several discussions in previous threads that support this information.
For your own benefit, please think Safety First!
