Can i fit a 2003 hemi crew cab 2500 engine and tranny into a 2004 hemi crew cab 1500, if there is anymore info i need to know please tell me and what years will the 2003 engine and tranny fit in?

 

I *think* it should drop right in, and hook right up........

 

Yes it will drop right in, HOWEVER...your 04 is setup for EGR and the 03 head and intake will not have the ports (or tube) for it. Can either custom tune to get rid of it or you'll have to punch the front of the head for it. Everything else should be plug and play, if you have any doubt with specific plugs or sensors not matching, use the original ones from the 04 so they match up with your harness.
