So I was at the junk yard the other day looking for some parts and i found a 2008 Cadillac that was burn really bad. All of the plastic part from the engine were melted and so has the electronic, anyway last time i was there there were selling a ls2 with 6,000 miles almost brand new for 1,800 asking price.So I think I can get this engine for a good price.Now how much of a hustle it is to get that engine ruining in a 2003 sierra.Will some of the electronics from my truck work on that engine.
