Noticable difference between 5.3 and 6.0?

Will I need injectors like you have? The cam listed above is close to yours right?

i'd get bigger injectors just to be on the safe side ! 42's are really cheap now days

If you are only looking for a 13 you can keep what you have and mod it, BUT like everyone once you get to a goal you will set another... So your 13 will become a 12... and so on. I vote save your wallet later down the road and go 6.0 I still wish I did!

im in the same boat, im working on getting a 2004 lq9 6.0 out of a ss truck with 44k miles. trying to get it for $1200. should be a nice step up from the 5.3 maybe get a nice set of l92 heads and raunchy cam with a decent shot of nitrous. with a 6 speed manual if i cant destroy all of 3rd gear and some of 4th with my 20's ill be very surprised. ill keep you posted.

going from a stock cammed 5.3 to a stock cammed 5.7 i went from 13.88 to 13.26.

yes you will feel a difference.

I went from a 4.8 to LQ9 so I can crime in. Don't let anyone tell you the difference is huge, it's not. Basically the 6.0 feels like the amount of power that should have come stock. The nicest difference for me was highway cruising power. The ability to go up any hill without dropping out of OD is nice. a 5.3 in a reg cab is probably very similar to the feel of a 6.0 in an ext. cab such as mine. The 5.3 is a very capable engine, as many have proven. That being said, I'm biased, and I would do the 6.0 swap

Im going to go with an lq4 and the torquer cam mentioned. Then if I need more power down the raod I can boost or spray.
