Alright tymann it's your lucky day cause I'm gonna help get ya on the right track.
1. Do you want to use the stock computer? If not, this opens up all kinds of doors for ya. Fast, Megasuirt, AEM etc can hook you up.
2. You'll need motor mounts, headers (all from TTI), intank fuel pump preferred but not necessary, although highly recomended.
3. Electric fan(s) depends on where and who you get a radiattor from, inlet/outlet hoses are on the same side for the 6.1 or car 5.7.
4. Stock computer can be programmed to due away with the auto trans so if this the way you go, contact Hotwireauto.com or Hotrodlane.cc or Bouchillonperformance.com or Modernmuscle.biz (dave weber is a hell of a nice guy). Either one of these places and probably more, can hook you up with a wiring harness for the stock application and it's plug and play also they can reprogram the computer.
Got more questions, just ask. Also do a search for Hemi swaps, you'll find all kinds of stuff.
