3G Hemi vs LSx vs Ford Mod Motor - which is the 'best'? And which to put in mopar?

Bill at RMS even makes mounts for the LS, he doesn't show them on his site but if you call he has them. I think that any LS headers that you could get your hands on should fit and any oil pan should work as the front of the suspension is ahead of the engine.

That's awesome that he's supporting the swap. You should start a build thread, though maybe on another site (less off topic banter, I would imagine). Shoot me a PM if you already have one or have pictures, etc.
