What about your tranny mount?
All of your mounts should have been replaced at once: doing some but not all increases the deterioration of the others. Which may be what you're feeling.
Did you do regular rubber type motor mounts or poly-urethane types? The poly ones transfer more vibrations to the chassis so you'll feel the engine more.

I think I may start a thread exclusively for Videos of what different setups sound like. I did it on Jeepforum it helped there we could probably benefit from it here
Basic info would be needed like header or stock manifold. Hiflow or stock cat. What brand muffler and piping. No comments other then that just sound clips.
