This is the basic dyno. The pillow blocks should align with the center of mass of the engine/reduction unit if any. The push rod that operates the scale is on an arm that is 1 foot from the centerline of the pillow blocks.

Put one on each side to account for reverse rotation.

 

A system for limiting travel of the engine mount both up and down is required to protect the scales when the engine shakes on shut down. Or locks up and tries to jump off of the stand.
