Hey !!! Have a 2011 Traverse with a seized engine --- ONLY 178.000 miles .... ( bummer ) .... Going to replace - but was wondering if anybody knows / has replaced with a newer year from that platform ?? ( ie. Traverse / Acadia / Enclave, etc. ) ..... Interchanges show 2011 can be only from 2009-2011, then 2012-2015....but in past experiences from other engine swaps, it could be that the long block is the same, and something just as simple as a different upper intake manifold or plenum was changed, and all you had to do was swap that part from the original engine to the new one and you were all set...... SOOOOOOOOO...... anybody have any knowledge ???????? Thanks in advance !!!!!!!!!!!!!
