I got an idea when I was changing the oil in my car today. Ive got a 2005 Chevy Malibu with the 3.5L V6. It just rolled over to 161,000 and I really like it, its a very reliable car and in very ggod shape. But my idea today was if the motor goes out in it, possibly swapping the motor out for the Supercharged 3.8L V6 that is in the ImpalaSS, and a few otherGM vehicles. My question is what would it take to do this motor swap for parts and other things, becauseI have never heard of this being done before.
