Because it works! The three replies with solid mounts are 2 BB & 1 SB engine with a wide range of HP and 2 different ways of mounting, all without issues. I guess I would reverse the question to "If you are having an issue with nonstandard flexable mounts, why would you not want to go to the as designed hard mounts?" Your helicopter experience has shown you to shim gaps and bolt up solid, that is exactly what we re doing with solid mounted side pipes. Remember, if you let it move, it is going to move. As mentioned above, the side pipes do have some flex, as well as the frame itself. Solid mounting will get everything moving together. If I were to go to a flexable mount, it would probably look similar to what you came up with, except I would probably go with studs welded to the frame as Rod suggested and bolt it up to the rubber spacer and leave off the spring. I cannot see how the springs would stop the torque of a 500 HP of engine from deflecting unless they were considerably heavier. I know how irratating it is to deal with persistent issues on the car and wish you well with your fix. Update us after your road tests.
