Not to a Hemi. Quick advice for you, the computers are a nightmare to navigate. I know first hand. Unless you are swapping in a CR from a donor truck and have the harnesses and computers (dash, etc) I would not suggest the Hemi/diesel swap. If you do, please keep us updated.
most likely, itll be cheaper to just buy/sell/trade yer current rig for a similar rig with a cr. now if youve happened upon a donor truck for cheap that might be ok. also think about the licensing and emissions of swapping
