It would fit but if you have never messed with pulling one of these engines or putting one of them in, especially trying to get one off in a Chevy Malibu, I would never even consider it. You would need lots of time and patience and money for it to work, not to mention a shop for it to set in until it's completed.
I'm all with chickens "hell no"
I would like to see one setting off in there though and good luck to you if you give it a go.
