This would put tension on the lower portion of the transmission mounting point and pressure on the upper, cast, bell. Hanging it from the bell on an engine stand places the reverse forces on it. The engine stand tries to hold it with fewer bolts unless an adapter is made such as Walt uses.
The 8BA engine doesn't have an attachment point below the block (except for the truck bell and oil pan connection) and is designed to support from the upper bolts. But there are six bolts holding the bell housing instead of the four on an engine stand.

Also, the oil pan helps to support the rear of the engine when it is in a car.
With good blocks getting so hard to find, why tempt fate with it? Doesn't make much sense to me.
