Billy22Bob,
So far the E55 style mounts are holding just fine. If one is blown, maybe I put it on the passenger side where it would simply get pushed further into the mount instead of pulling out.
I have not had time, nor the inclination to go further with this project. I am thinking the E55 mounts would be an excellent alternative that could take the abuse of some of the modified SRT6 engines on this forum.
Now I wonder if a set of E65 mounts would work... hmmm...
