[octaneautos]

Hey everyone! Happy Friday! I'm tinkering with a project this coming weekend, and wondering if any of you folks might have tried and failed, or has some advice... I am preparing to pull a 3.4 liter out of a 2005 equinox lt and replace it with a 3.9 liter from an 08 Impala. Will i have problems? Will the tranny mate up ok? Any reason why i shouldn't do it?? This could be a fun project with sweet results, or it could be a total pain in the ace! Any constructive input from you GM guys would be much appreciated!
