Either the rails need to be boxed or a common cross member must go from one side to the other, from one mount to the other. That will absorb the torque and keep the mounts from moving up or down at the engine end.

There has to be an cross-member involved to tie the frame rails together. The mounts I showed at first will not give that stability as shown in your diagrams.

Here's how the original Y-block bellhousing in a pickup transferred rotational torque to the frame, large mounts on both sides, in addition to a solid crossmember under the crank pulley.
