Best 5.7 to Dart

Hi Friend, I'm planing swap to 5.7 Hemi, my question is what is the best engine and year, Ram/Dakota or Charger/300C. I saw that the Ram/Dakota have the water oulet to the driver side and the Charger/300C to de other side.

Thanks.....Jose

Doesn't really matter, just go from an 04 to 08.
