hello everyone, my name i toni i have a 04' envoy 4.2 4wd with a blown engine and purchased a whole 06' envoy 4.2 4x4 for a good price with frame rot. i have read alot on doing the engine swap between the 2 and it seems doable but i can't seem to find an exact list of what will have to be changed/converted to do so. also i was wondering what i should do on the 06' engine before it is installed as to they aren't the easiest to work on while installed. thank you in advance for your time and any available help!
