    Do I stick with a 04+ motor or will any 3.8 supercharged motor work?

    L67 or L32 will both work, just swap your old stuff from intake manifold up over for the L67. I'd swap the crank sensor and balancer over too, to avoid having to do a case learn. Along with any accessories the replacement engine may not come with.

    Does it sound exactly like this?

    That sound was coming directly from the rear head and it turned out to be a worn valve guide.
