What is not to love...There are very few engines out there that will give you what the 5.3 does! You get over 300 hp and if you drive properly can get 20 mpg and over on the highway. On top of all that you still have a motor that will last 300,000 miles if properly taken care of! GM LS Series Engines are the most swapped motors for a reason!
I agree with you... From what I've read some of the early adopters had problems, but GM has made modifications to fix those problems. I've also read that this engine is sensitive to having clean oil. I'm not too worried with the 5y/100k warranty... Has anyone actually put 300k or even 150k on this engine yet?
