I have been back and forth on getting a 2500 burb with the 454 in it. I really don't want to give up my yukon, so I was thinking 454 in my yukon. I want it for more power and more or less to have the almighty 454 in my truck. Is this a possible swap? I know that changing motors is not an easy task I have done a few before. My problem is with all the computer controlled crap. Do I stand a chance? What do you guys think?
