Nice job! I have the same setup except mine's a 451 ;) and I used bushings as shown on the BBD tech pages. Not so much vibration (but still plenty!)

I like that! Is that a kit or did you have to make it? A few months ago I saw a local Duster with that type of mount on the HDK k-member but I figured it was all custom made.
That has to help with vibrations compared to being mounted solid.
