Tried doing a search on the above but didnt come back with anything. WHat do you people think of the above motor? I just bought a 2007 Malibu LTZ w/7500 miles on it. Seems like a solid engine. Is it comparable to the 3800 at all? I've heard this term "cam walk" I dont know to much about it, but have a rough idea. Is that common at all in the 3.5s?
