A Camaro site http://www.camaro5.com/forums/showth...?t=4736&page=3 had a lot of detailed info in old posts (from 2008) on the 3.6L engine including an undated GM marketing powerpoint slide (post 66) and a GM SAE J1349 engine dyno (post 67). Is this the identical engine that is in the 2010 CTS or were there changes from the engine shown in these posts.
