Homemade big block a body engine mounts

I like the simplicity of the mounts. I would be concerned about breaking the engine ears though. The tube adds leverage to the block mounts. If the bolt runs through both upper lugs it could potentially break an ear while tightening if the tube is not exact fit.
Looking at my phone without glasses though so I may have missed something.
I bet there is room everywhere. An advantage to solid mount. The spool mounts take up a lot of room and the biscuit mounts crowd the oil pump. In the big block conversation state.
