Has anyone considered the cost of a swap and all the time a headache involved, vs. building an improved 3.5? Wouldn't getting a re-man engine that already has the piston issues fixed and then its a direct bolt in swap be easier, cheaper and more reliable in the end?

I'm not against engine swaps, but I am a fan of the stock 3.5 and keeping the TOD seems to be a major concern for most people. I barely use TOD and leave my front hubs unlocked most of the time, so loosing it isn't much of a concern for me.

Also, on the whole Northstar V8 route. I would never want one of those piles in my engine bay. I've never seen one that doesn't leak and they are a nightmare to work on. The 3.8 V6's aren't bad, but I know they have plenty of their own problems with intake leaks and carbon build up.
