A friend had a low-side and the engine ran on a bit. 2 months later the same rod bearing seized. He took it apart and fixed it and then traded it on a new one. It's a pretty good piece of work just to pull one apart to assess damage. Most residual problems after such an incident stem from loose metal bits circulating in the lubrication system. I would disassemble completely and clean everything out before putting it back together with new parts. Again, a lot of work and big $ if you have to pay to have it done.
Have an '07 engine for sale if you're interested. <80,000 miles and runs perfect. Comes with Power Commander, throttle bodies and TRE. Can email video of it running.
It may be a pig, but it's a pig with a rocket in it's ass!
