Yea i'm thinking it's not worth it to mess around with the old motor when the technology of the lsx is so much more advanced. I'm trying to keep it around $1000 if possible, which is why i was leaning towards the 5.3. I'm not looking for insane power either, I'm perfectly happy with a solid 350 horses. I mostly am looking at it because it's like once you get it installed and tuned you never have to worry about it again. No setting timing or adjusting the carb, it just seems nicer that way. And from what i have read on different forums, the fuel mileage is a lot better. I'm hoping someone who has done and lsx swap can give me some actual mpg numbers.
