2014 GMC Acadia engine blown up

Hello I have this engine that is blown up I bought it as a wreck. Didnt know it was blown until several tows to the dealership. But I was looking online for a engine and I was wondering if engines out of earlier model cars will fit I found one they say it in a buick 08 to 2000 but it is a 3.6 I also found one that they say came from Dahmer powertrain engines its like a 2007 model I would really like to know if these will work for me or if I have to go with factory that I cant afford Thanks for any help
