Thread: Engine/Trans assembly swap

Ok have an update talked to a junkyard someone referred me to and they told me that the 05 has 220 CID and the 06-09 has 231 CID and that is apparently the difference so im sure it will work but the programming may not so there may in lie the problem. im just so confused as to why there would be a change in CID (cubic inch displacement) from 05 to 06 that sounds so stupid to me and not right.
